Using a Samsung Xpress C460FW with Gentoo Linux and Android KitKat for printing and scanning

INTRODUCTION

A work colleague has just received a Samsung Xpress C460FW MFP (laser printer, scanner, copier and fax machine) for small print jobs. It is possible to connect to it via USB, Direct USB, wired network, wireless network, Wi-Fi Direct and NFC; that’s impressive for a MFP that can be purchased for GBP 270 in the UK.

I wanted to use the C460FW to print and scan from my laptop running Gentoo Linux, and also to print and scan from my Samsung Galaxy Note 4 running Android KiKat. It turned out that I was able to do all of those, and it was not difficult to set up.

A technician from the IT Support department had already entered a static IP address, subnet mask and default gateway IP address via the C460FW’s control panel to connect it to the office’s wired network. So my options to connect to this particular C460FW are: the wired network for Linux; Wi-Fi Direct for Linux and Android; NFC for Android.

I had never used Wi-Fi Direct before, but it turned out to be easy in Gentoo Linux on my laptop, and also easy in Android KitKat on my Samsung Galaxy Note 4. I had never used NFC before either, and that also turned out to be easy on my Samsung Galaxy Note 4.

Samsung has a series of videos on YouTube explaining how to use Wi-Fi Direct and NFC for printing, scanning and faxing with the C460FW from a Samsung smartphone; here are links to a few of them:

PRINTING

Linux

Wired connection

I had installed the package net-print/samsung-unified-linux-driver Version 1.02 from a Portage local overlay back in March 2013 when I needed to print to a different model of Samsung MFP, so I thought I would see if that driver would work with the C460FW. I opened the CUPS Printer Manager in a browser window (http://localhost:631/) to configure my Gentoo installation to print to the device via the wired network. ‘Samsung C460 Series‘ was in the list of discovered network printers in the CUPS Printer Manager, and the driver ‘Samsung C460 Series PS‘ was displayed at the top of the list of models, so it was a piece of cake to set up the printer via CUPS, and I was able to print a test page in no time at all. My colleague uses a laptop running Windows 7, and he had to install the Windows driver from a Samsung CD that came with the C460FW.

Wireless connection

As the IT Support technician had configured the C460FW to print via the office wired network rather than the office wireless network, I decided to configure my laptop to print via Wi-Fi Direct, just to learn about Wi-Fi Direct, really. On the C460FW’s control panel I selected Network > Wireless > Wi-Fi Direct and enabled Wi-Fi Direct. Scrolling through the Wi-Fi Direct entries in the LCD I saw the following information:

Device Name: C460 Series
Network Key: <an 8-digit code>
IP address: 192.168.003.001

Two new networks were listed under ‘Available connections’ in plasma-nm (the KDE GUI front-end to NetworkManager) on my laptop: ‘DIRECT-HeC460 Series‘ and ‘DIRECT-SqC460 Series‘, both using WPA2-PSK encryption. I used the control panel of the C460FW to print a network configuration report in order to check which of the two SSIDs I should select, and it is ‘DIRECT-HeC460 Series‘ (I found out later that an adjacent room also has a C460FW and its Wi-Fi Direct SSID is ‘DIRECT-SqC460 Series‘). So I selected ‘DIRECT-HeC460 Series‘ and plasma-nm prompted me to enter a network password. I entered the 8-digit key I had found from the C460FW’s LCD panel (it’s also listed in the printed network configuration report), and NetworkManager connected to the printer.

In exactly the same way as I do when setting up any printer in Linux, I launched Firefox, opened the CUPS Printer Manager page, clicked on ‘Administration’ > ‘Add Printer’ and entered the user name ‘root’ and the password in the pop-up window. Again the ‘Add Printer’ page had ‘Samsung C460 Series‘ in the list of discovered network printers, so I just selected it and clicked on ‘Continue’. As I had already set up the printer in CUPS for the wired network connection and given it the name ‘Samsung_C460FW_office‘, I entered the name ‘Samsung_C460FW_office_WiFi_Direct‘ to distinguish it from the wired network entry, entered a Description and Location, and clicked on ‘Continue’. The next page had ‘Samsung C460 Series PS‘ first in the driver list so I selected that, clicked on ‘Add Printer’ and that was it. I was able to print a test page from the CUPS Printer Manager, and the printer is now included the list of printers in Linux applications’ print dialogues.

When I want to print using Wi-Fi Direct the only thing I need to remember to do first is select ‘DIRECT-HeC460 Series‘ in the network GUI on the KDE Panel, so that the connection is active when I click ‘Print’ in whichever application I want to print from.

Given the ease of printing via the wired network and Wi-Fi Direct, I have no doubts that printing would also work had the C460FW been configured for the office wireless network instead of the wired network.

Duplex printing

The only downside to the Samsung Xpress C460FW is that it only supports manual duplex printing. If you specify duplex printing when printing from Windows, Samsung’s Windows driver prints all the odd-numbered pages in reverse order and displays a message in Windows telling you what to do next (turn over the pile of paper and put it back in the paper tray!), but in Linux it’s not difficult to work out what you have to do: you simply have to print all the odd-numbered sides first, turn over the paper, then print all the even-numbered sides. The print dialogue in Linux applications gives you the option to print only odd-numbered pages or only even-numbered pages, so there is no problem. The print dialogue in some Linux applications allows you to print pages in reverse order as well but, if not, you have to reverse the order yourself before printing the even-numbered pages (i.e. put Page 1 face down at the top of the pile then Page 3 face down under it, and so on). It’s not a big deal unless the document has a large number of pages.

Android

As you would expect with devices from the same manufacturer, setting up my Samsung Galaxy Note 4 to print with the Samsung Xpress C460FW via WPS (Wi-Fi Protected Setup) was easy. When I selected ‘Print’ on the Galaxy Note 4, it gave me the option to print via wireless network or Wi-Fi Direct. I chose the latter and, as I had already enabled Wi-Fi Direct on the C460FW’s control panel, the printer name was displayed in the list of available devices. I selected it, a blue LED began flashing on the C460FW’s control panel and the LCD prompted me to press the WPS button (on the left of the control panel). As soon as I pressed that, the C460FW printed the document sent by my Galaxy Note 4. From then onwards, I just needed to select ‘Print’ on the Galaxy Note 4, select the printer from the list of available devices, and the document is printed. When I want to print using Wi-Fi Direct the only thing I need to remember to do first on the Galaxy Note 4 is select ‘DIRECT-HeC460 Series‘ as the Wi-Fi network.

NFC

I then decided to try to print using NFC. I placed the Galaxy Note 4, without Wi-Fi enabled and with the Home Screen displayed (not the Lock Screen), on the NFC label on top of the C460FW; Android launched Play Store and prompted me to install Samsung Mobile Print, which I did. Now when I place the Galaxy Note 4 on the NFC label, the Galaxy Note 4 automatically enables Wi-Fi, connects to the C460FW directly and displays the Mobile Print app showing the options Print, Scan and Fax, and a page of icons labelled: Gallery, Camera, Google Drive, E-mail, Web page, Document, Facebook, DropBox, Evernote, OneDrive and Box, as well as a Settings icon to configure the printer (paper size etc.). I am able to select a document, photograph, Web page, etc. on the Galaxy Note 4 and print it. It is also possible to launch the Mobile Print app first and then place the Galaxy Note 4 on the C460FW.

NFC is not entirely trouble-free, though. Sometimes the Galaxy Note 4 displays a ‘Device not found‘ message but I can still print. Sometimes the Galaxy Note 4 displays the message ‘Connecting printer. There was some error while connecting to this device. Check your printer and try again. If NFC Pin was changed then please enter new NFC Pin.‘ and the two devices will not connect. Powering off then on the C460FW solves that. Sometimes the Galaxy Note 4 connects to another wireless network instead of to the C460FW via Wi-Fi Direct and the Samsung Galaxy Note 4 then has to disconnect automatically from the other network. Sometimes the C460FW prompts me to press its WPS button and the Galaxy Note 4 then connects via Wi-Fi Direct but the Mobile Print app then displays the error message ‘Device not found. To troubleshoot please check – C460 Series is powered on. – Wi-Fi direct is enabled on C460 Series. – C460 Series and Mobile are connected to the same network.‘. Again, powering off then on the C460FW solves that. Despite these hiccups, printing via NFC is still handy.

SCANNING

Linux

I found out how to get the C460FW scanner working by consulting the third-party Web site The Samsung Unified Linux Driver Repository which someone created to provide .deb packages for the Samsung driver as well as tips on how to get Samsung printers and scanners working in Linux. It turned out to be relatively straightforward to scan, both via the office wired network and via Wi-Fi Direct. I edited the file /etc/sane.d/xerox_mfp.conf and replaced the following:

#Samsung C460 Series
usb 0x04e8 0x3468

with the following in order to use the C460FW to scan via the office wired network:

#Samsung C460 Series
#usb 0x04e8 0x3468
#Wired network static address of this C460FW:
tcp 10.90.21.125

or with the following in order to use the C460FW to scan via Wi-Fi Direct:

#Samsung C460 Series
#usb 0x04e8 0x3468
#Wi-Fi Direct address of this C460FW:
tcp 192.168.3.1

I found the IP addresses from the network configuration report I printed earlier.

I was able to use the two Linux scanning applications I normally use, XSane and gscan2pdf, to scan via the wired network and via Wi-Fi Direct. The resulting scans were very good. Given the ease of scanning via the wired network and Wi-Fi Direct, I have no doubts that scanning would work via a wireless network had the C460FW been configured for the office wireless network instead of the wired network.

Android

To use NFC to scan a document I place the Galaxy Note 4, without Wi-Fi enabled and with the Home Screen displayed (not the Lock Screen), on the NFC label on top of the C460FW. The Galaxy Note 4 enables Wi-Fi, connects automatically to the C460FW directly and launches the Mobile Print app showing the options Print, Scan and Fax. It is also possible to launch the Mobile Print app first and then place the Galaxy Note 4 on the C460FW. In other words, the procedure is exactly the same as when wanting to print via NFC. If I select Scan, the Galaxy Note 4 displays buttons for previewing and scanning. Amongst other things, the app’s Settings menu allows you to select whether you want to save the scanned image as a JPEG, PNG or PDF file. The hiccups mentioned above when printing via NFC also apply to scanning. Nevertheless, scanning from the C460FW to the Samsung Galaxy Note 4 via NFC is still handy.

CONCLUSION

As I am mainly interested in printing text documents I have only tried to print a few colour photographs on plain copier paper, and they look good. Text in documents looks crisp. Despite the lack of automatic duplex printing the C460FW is an excellent peripheral, especially for the price, although I don’t pay for the consumables so I have no idea of the operating costs. The ease with which I got it printing and scanning in Gentoo Linux (laptop) and Android KitKat (Samsung Galaxy Note 4) means that I would definitely consider purchasing this model for home use.

Not able to access the CUPS Printer Manager in Firefox when, or after, using a proxy server

Just a quick tip if you are trying to use the CUPS Printer Manager in a Firefox browser window (http://localhost:631/) to add a printer, manage a printer or view print jobs but the brower displays a message such as ‘Connecting to 10.48.80.49…’ and eventually times out and displays the following message:

 Network Error (tcp_error)

A communication error occurred: “Operation timed out”
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

For assistance, contact your network support team.

or the following message:

Unable to connect

Firefox can’t establish a connection to the server at 10.48.80.49.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

    Try Again

This sometimes happens to me when my laptop is connected to a corporate network and the browser is, or recently was, configured to use a proxy server. Anyway, in Firefox I select ‘Open menu’ > ‘Preferences’ > ‘Network’ > ‘Settings…’ and make sure ‘No proxy’ is selected, then I select ‘Open menu’ > ‘Preferences’ and click on the ‘Clear Now’ button for ‘Cached Web Content’ (I have to click twice to clear the cache, for some reason) and the ‘Clear Now’ button for ‘Offline Web Content and User Data’. After doing this, I can access all the CUPS Printer Manager pages in the browser again.

NetworkManager creates a new connection ‘eth0′ that does not work

Several months ago a new entry ‘eth0′ began appearing under ‘Available connections‘ in the KDE plasma-nm widget (the KDE GUI front-end to NetworkManager) in my Gentoo Linux installation. However, there was already an automatically-created entry ‘Wired connection 1′ for the wired interface. In the plasma-nm GUI I could see that both entries were for the same interface (eth0) and MAC address. My laptop could access the Internet via the connection ‘Wired connection 1′ as usual, but not via the new connection ‘eth0′. And if I deleted ‘eth0′ in the plasma-nm GUI, ‘Wired connection 1′ could not access the Internet until I recreated ‘eth0′ manually.

Apart from the fact that two entries for the same interface is unnecessary, it was annoying because sometimes ‘eth0′ automatically became the active connection instead of ‘Wired connection 1′, despite the fact that only ‘Wired connection 1′ had ‘Automatically connect to this network when it is available’ ticked in the plasma-nm GUI. When this happened, the network icon on the Panel showed an active connection but in fact the laptop could not connect to the Internet. However, the connection did work as expected on the occasions when ‘Wired connection 1′ automatically became the active connection or if I switched manually to ‘Wired connection 1′ via the plasma-nm GUI.

Even more strangely, if I happened to be using WiFi when no Ethernet cable was connected, very occasionally the network icon on the Panel would change from a wireless icon to a wired icon and connection to the Internet would be lost. I would then have to re-select the wireless network in order to reconnect to the Internet.

As my laptop has only one Ethernet port, and as there was previously no ‘eth0′ entry under ‘Available connections‘, initially I thought that the new entry occurred because I had recently installed a new version of udev. I have the parameter net.ifnames=0 in the kernel boot line to stop udev/eudev using the so-called Predictable Network Interface Names, and I have the following udev/eudev rules files relating to networking:

# ls -la /etc/udev/rules.d/*net*
lrwxrwxrwx 1 root root    9 Nov 30 15:25 80-net-setup-link.rules -> /dev/null
# ls -la /lib64/udev/rules.d/*net*
-rw-r--r-- 1 root root  452 Nov  7 09:57 /lib64/udev/rules.d/75-net-description.rules
-rw-r--r-- 1 root root 1734 Jan 28 18:29 /lib64/udev/rules.d/77-mm-huawei-net-port-types.rules
-rw-r--r-- 1 root root  491 Nov  7 09:57 /lib64/udev/rules.d/80-net-name-slot.rules
-rw-r--r-- 1 root root  280 Jan 24 00:41 /lib64/udev/rules.d/90-network.rules

Perhaps udev (well, eudev, as I switched to using eudev after the problem started) did have something to do with the new entry, but I began to suspect that NetworkManager was the culprit. I think the problem first occurred after installing NetworkManager 0.9.10.0 last October, but it remained after I installed NetworkManager 1.0.0, until today when I made the various changes described further on.

I had merged NetworkManager 1.0.0 and preceding versions since 0.9.8.8 with USE flags -dhclient and dhcpcd, i.e. NetworkManager in my installation uses the DHCP client dhcpcd instead of dhclient. (I used to merge NetworkManager to use dhclient but found it did not work with 0.9.8.8 and later versions of NetworkManager.)

The relevant network services running in my installation are as follows, and nothing looks incorrect to me:

# rc-update show | grep -i net
       NetworkManager |      default
                local |      default nonetwork
               net.lo | boot
             netmount |      default
# rc-status | grep -i net
NetworkManager                                                    [ started ]
netmount                                                          [ started ]
# rc-update show | grep dh
# rc-status | grep dh
# rc-update -v show | grep supplicant
wpa_supplicant |
# rc-status | grep supplicant
#

NetworkManager itself launches the DHCP client, so the installation should not be configured to launch a DHCP client. Indeed the output above shows that no DHCP client service is configured to run independently of NetworkManager, and I also double-checked that multiple instances of a DHCP client are not running (they’re not):

# ps -C NetworkManager
  PID TTY          TIME CMD
 6481 ?        00:00:22 NetworkManager
# ps -C dhcpcd
  PID TTY          TIME CMD
10378 ?        00:00:00 dhcpcd
# ps -C dhclient
  PID TTY          TIME CMD
#

As far as WiFi is concerned, NetworkManager itself launches wpa_supplicant, so the installation should not be configured to launch wpa_supplicant. Indeed the output from rc-update and rc-status above shows that no wpa_supplicant service is configured to run independently of NetworkManager, and I also double-checked that multiple instances of wpa_supplicant are not running (they’re not):

# ps -C wpa_supplicant
  PID TTY          TIME CMD
 6491 ?        00:00:00 wpa_supplicant
#

So, as far as I could tell, there was nothing wrong with the non-NetworkManager side of my installation.

I thought the problem might be due to the settings in the file /etc/NetworkManager/NetworkManager.conf, which contained the following:

[main]
plugins=keyfile
dhcp=dhcpcd

[ifnet]
managed=true
auto_refresh=false

[keyfile]
hostname=meshedgedx

I studied the manual pages for NetworkManager.conf:

# man NetworkManager.conf

If I understand correctly, the ifnet plug-in is Gentoo-specific (see References 3, 4 and 5 further on). The entries under [ifnet] in my NetworkManager.conf file were redundant in any case because the ifnet plug-in was not included in the plugins list under [main], so I deleted the entire [ifnet] section. There is no mention of the ifnet plug-in on the NetworkManager.conf manual page or in the Gentoo Linux Wiki article on NetworkManager, and a cursory look in the Gentoo ebuild for NetworkManager 1.0.0 clearly indicates the ifnet plug-in is broken. See, for example, the following comment in the ebuild:

# ifnet plugin always disabled until someone volunteers to actively
# maintain and fix it

and the following warning messages in the ebuild if the user has included ifnet in plugin=<plugin list> in NetworkManager.conf:

ewarn "Ifnet plugin is now disabled because of it being unattended"
ewarn "and unmaintained for a long time, leading to some unfixed bugs"
ewarn "and new problems appearing. We will now use upstream 'keyfile'"
ewarn "plugin."
ewarn "Because of this, you will likely need to reconfigure some of"
ewarn "your networks. To do this you can rely on Gnome control center,"
ewarn "nm-connection-editor or nmtui tools for example once updated"
ewarn "NetworkManager version is installed."
ewarn "You seem to use 'ifnet' plugin in ${EROOT}etc/NetworkManager/NetworkManager.conf"
ewarn "Since it won't be used, you will need to stop setting ifnet plugin there."

I modified NetworkManager.conf to contain the following:

[main]
plugins=keyfile
dhcp=dhcpcd
no-auto-default=eth0

[keyfile]
hostname=meshedgedx

Note that the ifnet plug-in was not specified in the plugins list in the [main] section of my previous NetworkManager.conf so it was not the cause of my problem, but I hoped that adding no-auto-default=eth0 to NetworkManager.conf would solve the problem. I deleted the ‘Wired connection 1′ entry from the plasma-nm GUI, ticked ‘Automatically connect to this network when it is available’ for the ‘eth0′ entry and made sure that option was not ticked for any of the other entries under ‘Available connections‘, then rebooted. There was no longer an entry ‘Wired connection 1′ in the plasma-nm widget GUI, just an entry for ‘eth0′, and the installation connected automatically to the wired network and I could access the Internet, but did not reconnect to the wired network if I removed and reinserted the Ethernet cable when also connected to a wireless network. So I was not home and dry yet.

I have read on various Web sites that NetworkManager prefers wired connections over wireless connections. I assume this is because NetworkManager sets a higher metric for the wired connection.

I am on a work trip at the moment and cannot use a dynamic wired connection, only a static wired connection, but I can see that NetworkManager 1.0.0 does set a higher-priority metric for wired connections:

# # Now with both dynamic wireless and static wired:
# ip route show
default via 10.90.21.1 dev eth0  proto static  metric 100
default via 10.96.0.1 dev wlan0  proto static  metric 600
10.90.21.0/24 dev eth0  proto kernel  scope link  src 10.90.21.112  metric 100
10.96.0.0/16 dev wlan0  proto kernel  scope link  src 10.96.87.86
10.96.0.0/16 dev wlan0  proto kernel  scope link  src 10.96.87.86  metric 303
127.0.0.0/8 dev lo  scope host
127.0.0.0/8 via 127.0.0.1 dev lo
192.0.2.1 via 10.96.0.1 dev wlan0  proto dhcp  metric 600
#

10.90.21.1 is the IP address of the gateway for the wired connection, and 10.90.21.112 is the IP address of my laptop’s wired interface. The smaller the metric value, the higher the routing priority. Notice that the metric for the eth0 interface is 100 whereas the metric for the wlan0 interface is 600, so it does appear that NetworkManager favours a wired connection over a wireless connection when both are active.

After doing all the above, I came across Debian bug report no. 755202: network-manager: keeps creating and using new connection “eth0″ that does not work which appears to be exactly what I was experiencing. Various people posted solutions that worked in their particular circumstances, so I am none the wiser. Gentoo user Keivan Moradi posted message no. 79 on that bug report, about a warning message he found in the NetworkManager log file regarding a file /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0, and he then deleted the latter file. I found the same message in /var/log/messages:

# grep networkmanager /var/log/messages
Feb  9 04:10:05 localhost NetworkManager[10355]: <warn>      error in connection /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0: invalid connection: connection.type: property is missing
Feb 11 15:53:05 localhost NetworkManager[13143]: <warn>      error in connection /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0: invalid connection: connection.type: property is missing

The file /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0 also existed in my installation, so I also deleted it. It was a zero-length file and I do not know if it had anything to do with my problem:

# ls -la /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0
-rw------- 1 root root 0 Jan 20 00:09 /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0
# rm /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0
#

Anyway, the file /etc/NetworkManager/system-connections/.keep_net-misc_networkmanager-0 has not reappeared since I deleted it.

Keivan Moradi had ‘id=Wired‘ under [connection] in the file /etc/NetworkManager/system-connections/eth0, and he decided to change the name of the file from ‘eth0‘ to ‘Wired‘. However, in my case the file name and the id in the file /etc/NetworkManager/system-connections/eth0 are both ‘eth0‘:

# cat /etc/NetworkManager/system-connections/eth0
[ethernet]
mac-address=70:5A:B6:3E:C1:8A
mac-address-blacklist=

[connection]
id=eth0
uuid=cb3d5786-f947-44b8-92f7-8471fc94c568
type=ethernet
permissions=
secondaries=

[ipv6]
method=ignore
dns-search=

[ipv4]
method=auto
dns-search=

I had already deleted and recreated the connection ‘eth0′ in the plasma-nm GUI by the time I checked the contents of the directory /etc/NetworkManager/system-connections/ so I do not know if the original file name and id were the same. I had also already deleted the connection ‘Wired connection 1′ in the plasma-nm GUI by the time I checked the contents of the directory; presumably files for connections ‘Wired connection 1′ and ‘eth0′ both existed in /etc/NetworkManager/system-connections/ before then. I do not know why the zero-length file .keep_net-misc_networkmanager-0 was created, but no further files have appeared in the directory since I deleted the connection ‘Wired connection 1′ and the file .keep_net-misc_networkmanager-0.

Keivan Moradi was also previously using a buggy r8169 kernel module (Realtek Ethernet hardware) and switched to using the r8168 module, but I am using a Qualcomm Atheros AR8131 Gigabit Ethernet card and an Intel Corporation Ultimate N WiFi Link 5300 card, so that part of his problem cannot be a factor in my case.

Anyway, as I wrote earlier, I no longer have two connection entries for the wired interface, and NetworkManager no longer creates automatically a second connection entry for the wired interface. And now if I am already connected to a wireless network, NetworkManager connects/reconnects automatically to a wired network with the ‘Automatically connect’ option ticked. So it looks like my problem is completely solved, although I reserve judgement until I have been able to use the laptop in my home network (which has the same router for both wired and wireless connections, whereas the wired network and wireless network are separate networks in the office in which I am now working).

Conclusion

If you had the patience to read all the above, I am impressed! If you also understood it, I am doubly impressed!

To cut a long story short, if you are experiencing a similar problem to mine, I recommend you do the following:

  1. Check that your network driver is reliable. You can search the Web to see if other users have experienced problems with the same driver you are using.

  2. Make sure the contents of NetworkManager.conf are correct. Read the NetworkManager.conf man page and the GNOME Wiki page on NetworkManager settings to find out what options are available.

  3. Delete all the files (i.e. including hidden files) in the directory /etc/NetworkManager/system-connections/ and recreate your connections via either the NetworkManager GUI (e.g. plasma-nm in KDE or nm-applet in GNOME) or NetworkManager TUI (nmtui).

Samsung Galaxy Note 4

I owned a Samsung Galaxy Note II since October 2012 and had been very pleased with it, although recently I had been finding it a little slow when needing a fast response at work, and performance of the camera in low light could have been a bit better. The launch of the Galaxy Note 4 last October piqued my interest, and I finally succumbed to temptation and bought one last week. I have to say I am impressed with Clove Technology: I ordered the smartphone via the Internet at 00:02 on 22 January and it was delivered to my house on 23 January. I ordered the UK model (SM-N910F), and you can find the Samsung user manual for that model on the Samsung Support page.

The smartphone has so many features and options that you really need to study the manual and watch some tutorial videos in order to get the most out of it. If you don’t, you’ll be missing out on several extremely powerful tools. I spent some time trawling YouTube for tutorial videos; below I list the ones I found the most useful, in no particular order. Several of them cover mostly the same ground, but usually there is a tip in one that is not in another so it pays to watch them all eventually. In any case, repetition helps reinforce the learning process.

Fixing unperceived errors in my X Windows configuration

Prologue

Last week I decided to bite the bullet and upgrade X Windows to the latest version available in the main Portage tree: 1.16.3-r1. I updated my entire installation (I ‘emerged world’, in Gentoo parlance). The package eselect-opengl was one of various other packages updated as well (it was updated to Version 1.3.1-r1). Fortunately I scan the Gentoo Forums regularly and noticed the threads ‘new x11 update breaks glx‘ and ‘After xorg-server-1.16.2.901-r1 update 3D stopped working‘, so I was forewarned that a "Files" section is not allowed in more than one X Windows configuration file if an installation has more than one (e.g. /etc/X11/xorg.conf and /etc/X11/xorg.conf.d/*.conf). The eselect-opengl ebuild was subsequently bumped to 1.3.1-r2 to display a warning to users regarding this restriction.

I’m using ~amd64 multilib and the FGLRX driver (ATI Mobility Radeon HD 5650 GPU). Before updating, my laptop’s installation had a file /etc/X11/xorg.conf and no /etc/X11/xorg.conf.d/ directory.

Before updating I cleaned up a few broken symlinks (indicated by flashing red text in Konsole) relating to the FGLRX driver — presumably left over from previous updates several years ago judging by the file dates — that I found during a cursory search:

# ls -la /usr/lib32/xorg/modules/extensions/
# rm /usr/lib32/xorg/modules/extensions/fglrx-libglx.so
# rm /usr/lib32/xorg/modules/extensions/libglx.so
# ls -la /usr/lib64/xorg/modules/extensions/
# rm /usr/lib64/xorg/modules/extensions/FGL.renamed.libglx.so
# rm /usr/lib64/xorg/modules/extensions/fglrx-libglx.so

(There may have been other broken symlinks relating to the FGLRX driver and GLX, but I didn’t look further.)

Then I updated all packages using the Portage command ‘emerge -uvDN --keep-going world‘ as usual. After the update was complete, the contents of the file /etc/X11/xorg.conf included the following two consecutive lines:

Section "Files"
EndSection

and there is a new directory /etc/X11/xorg.conf.d/ which contained a single file 20opengl.conf with only five lines:

Section "Files"
        ModulePath "/usr/lib32/xorg/modules"
        ModulePath "/usr/lib64/opengl/ati"
        ModulePath "/usr/lib64/xorg/modules"
EndSection

Heeding posts in the aforementioned two Gentoo Forums threads I deleted the above-mentioned two lines in xorg.conf and I also deleted the first ModulePath (the one with ‘lib32‘) in 20opengl.conf. After rebooting, X Windows, GLX and Direct Rendering worked fine as usual. (I subsequently discovered it is not necessary to delete that ModulePath in my case, as there are no longer any files in /usr/lib32/xorg/modules and its subdirectories in my case.)

So everything was good. Well, not quite. Although the installation was working properly, there were still some long-standing messages in the X.Org log file /var/log/Xorg.0.log that indicated my installation was not configured completely correctly. I had ignored them for too long and resolved to find their causes and eliminate them. Here is what I did.

AIGLX error message

The contents of log file Xorg.0.log included the following error message:

(EE) AIGLX error: failed to open /usr/X11R6/lib64/modules/dri/fglrx_dri.so, error[/usr/X11R6/lib64/modules/dri/fglrx_dri.so: cannot open shared object file: No such file or directory]

Despite the error message, AIGLX was working, but I resolved to get rid of the message anyway by creating a symlink for the missing file mentioned in the message:

# ls /usr/X11R6/lib64/modules
extensions
# mkdir -p /usr/X11R6/lib64/modules/dri/
# ls -la /usr/lib/dri/fglrx_dri.so
-rwxr-xr-x 1 root root 37365968 Jan 10 18:16 /usr/lib/dri/fglrx_dri.so
# ln -s /usr/lib/dri/fglrx_dri.so /usr/X11R6/lib64/modules/dri/fglrx_dri.so
# cd /usr/X11R6/lib64/modules/dri
# ls -liat
total 8
2229069 drwxr-xr-x 2 root root 4096 Jan 22 22:30 .
2230340 lrwxrwxrwx 1 root root 25 Jan 22 22:30 fglrx_dri.so -> /usr/lib/dri/fglrx_dri.so
685665 drwxr-xr-x 4 root root 4096 Jan 22 22:29 ..

Now there is no error message and functionality has not been affected:

# grep -i GLX /var/log/Xorg.0.log
[ 30.773] (II) "glx" will be loaded by default.
[ 31.098] (II) LoadModule: "glx"

[ 31.167] (II) Module glx: vendor="Advanced Micro Devices, Inc."
[ 38.949] (II) AIGLX: Loaded and initialized OpenGL driver(II) GLX: Initialized DRI GL provider for screen 0

Touchpad

In looking through /var/log/Xorg.0.log I noticed some messages (not all contiguous) relating to the touchpad which indicated there were other problems:

[    31.940] (**) |-->Input Device "SynapticsTouchpad"
[    32.538] (II) LoadModule: "synaptics"
[    32.538] (II) Loading /usr/lib64/xorg/modules/input/synaptics_drv.so

[    41.282] (EE) PreInit returned 11 for "SynapticsTouchpad"
[    41.282] (II) UnloadModule: "synaptics"

The touchpad was working fine, but I didn’t understand why the synaptics module was being loaded twice, then unloaded. Also, the message about an undetectable ‘protocol’ indicated a problem.

Now, as I mentioned at the beginning of this post, previously my installation did not have the directory /etc/X11/xorg.conf.d/ and there was only the file /etc/X11/xorg.conf. Below is what xorg.conf contained before I updated:

EndSection

The only mention of a ‘protocol’ in xorg.conf was the line:

Option	    "Protocol" "auto-dev"

Searching the Web soon showed me that auto-dev is obsolete (Debian Bug report #649003 – xserver-xorg-input-synaptics: Option “Protocol” “auto-dev” does not work anymore – documentation needs fixing), so I simply deleted that line from xorg.conf. Another error message eliminated, but several more to go.

I knew that, since Version 1.8 (I believe that was the release), X Windows allows the use of /etc/X11/xorg.conf.d/*.conf files instead of, or as well as, /etc/X11/xorg.conf as a means of configuring X Windows (see e.g. Gentoo Xorg-server 1.8 Upgrade Guide).

As my latest installation update had resulted in the creation of the directory /etc/X11/xorg.conf.d/, I decided to move the touchpad configuration from the xorg.conf file to a new file in that directory, and therefore I created the file /etc/X11/xorg.conf.d/50-synaptics.conf containing the following:

Section "InputClass"
        Identifier "touchpad"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "0"
        Option "EmulateTwoFingerMinZ" "40"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "35"
        Option "FingerHigh" "40"
EndSection

However the log file Xorg.0.log still contained messages such as the following:

[    41.535] (**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall"

Notice that I had named the InputClass "touchpad" in the file /etc/X11/xorg.conf.d/50-synaptics.conf, not "evdev touchpad catchall", so I began to wonder if X Windows configuration files existed in other directories and were also being parsed by X Windows. I searched and found three in the directory /usr/share/X11/xorg.conf.d/:

# ls /usr/share/X11/xorg.conf.d/
10-evdev.conf  10-quirks.conf  50-synaptics.conf

These three files contained, respectively, the following:

EndSection

Looking at the InputClass section names and the messages in Xorg.0.log, the penny dropped: X Windows uses all the configuration files it finds in the /usr/share/X11/xorg.conf.d/,  /etc/X11/ and /etc/X11/xorg.conf.d/ directories. I had not realised this before; I had simply assumed X Windows only uses configuration files in the latter two directories (I should have looked more closely in Xorg.0.log, as it mentions /usr/share/X11/xorg.conf.d/). So I did the following:

1.  Deleted the file /usr/share/X11/xorg.conf.d/50-synaptics.conf (my laptop does not have a clickpad, so I don’t need the sections relating to a clickpad anyway).

2.  Modified the file /etc/X11/xorg.conf.d/50-synaptics.conf to contain the parts of /usr/share/X11/xorg.conf.d/50-synaptics.conf that stop X Windows assuming the touchpad is a mouse (udev detects it as a mouse in addition to detecting it as a touchpad):

 
Section "InputClass"
        Identifier "touchpad catchall"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "1"
        Option "TapButton2" "2"
        Option "TapButton3" "3"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "0"
        Option "EmulateTwoFingerMinZ" "40"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "35"
        Option "FingerHigh" "40"
EndSection

Section "InputClass"
        Identifier "touchpad ignore duplicates"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/mouse*"
        Option "Ignore" "on"
EndSection

Notice that I also changed the Identifier of the first section from “touchpad” to “touchpad catchall”, although I could have left it as it was.

Note that the following pair of messages in the file /var/log/Xorg.0.log do not worry me, as I believe they indicate that an InputClass section named "touchpad ignore duplicates" in an X Windows configuration file made X Windows ignore udev when it detected the touchpad again, this time as a mouse instead of a touchpad. As X Windows has already loaded the synaptics module for the touchpad device /dev/input/event5 (it could be a different event number in your case), it is therefore correct to make the synaptics driver ignore /dev/input/mouse*.

[    41.581] (II) config/udev: Adding input device SynPS/2 Synaptics TouchPad (/dev/input/mouse0)
[    41.581] (**) SynPS/2 Synaptics TouchPad: Ignoring device from InputClass "touchpad ignore duplicates"

3.  Moved the file /etc/X11/xorg.conf.d/10-evdev.conf to /etc/X11/xorg.conf.d/10-evdev.conf and edited it to contain the following:

Section "InputClass"
        Identifier "evdev pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Note that I removed the section "evdev touchpad catchall" because I believe its purpose is already covered by the section "touchpad catchall" in the file /etc/X11/xorg.conf.d/50-synaptics.conf.

Actually, as my laptop does not have a tablet connected and neither does it have a touchscreen, I could also have removed the last two sections, but I left them in as they would do no harm.

4.  Checked in the file /var/log/Xorg.0.log which modules loaded by /etc/X11/xorg.conf are loaded anyway, and therefore do not need to be included in xorg.conf:

The module vbe was the only one being loaded exclusively because of a Load command in the xorg.conf file.

5.  Edited /etc/X11/xorg.conf to: a) remove the unecessary loading of those modules that are already being loaded; b) remove the section relating to the touchpad, as I had moved it to /etc/X11/xorg.conf.d/50-synaptics.conf:

Section "ServerLayout"
        Identifier     "Main Layout"
        Screen      0  "aticonfig-Screen[0]-0" 0 0
EndSection

Section "Module"
        Load  "vbe"
EndSection

Section "ServerFlags"
        Option      "AllowMouseOpenFail" "true"
EndSection

Section "Monitor"
        Identifier  "aticonfig-Monitor[0]-0"
        Option      "VendorName" "ATI Proprietary Driver"
        Option      "ModelName" "Generic Autodetecting Monitor"
        Option      "DPMS" "true"
EndSection

Section "Device"
        Identifier  "aticonfig-Device[0]-0"
        Driver      "fglrx"
        BusID       "PCI:1:0:0"
EndSection

Section "Screen"
        Identifier  "aticonfig-Screen[0]-0"
        Device      "aticonfig-Device[0]-0"
        Monitor     "aticonfig-Monitor[0]-0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth    24
        EndSubSection
EndSection

Section "DRI"
        Mode         0666
EndSection

According to the xorg.conf(5) manual page:

Option “AllowMouseOpenFail”boolean

This tells the mousedrv(4) and vmmouse(4) drivers to not report failure if the mouse device can’t be opened/initialised. It has no effect on the evdev(4) or other drivers. Default: false.

so I left the section ServerFlags in xorg.conf, as the global X.Org Server option "AllowMouseOpenFail" does no harm. I could have deleted it, though.

6.  I left /usr/share/X11/xorg.conf.d/10-quirks.conf as it was, because there is nothing in it that relates to the specific hardware in my laptop. I could have just deleted the file.

Outcome

Now that I have removed the superflous X windows configuration files with some duplicate sections, /var/log/Xorg.0.log no longer contains duplicate messages relating to the touchpad and evdev. As I have also removed superflous module-loading commands from xorg.conf, there are also no longer any messages regarding already-loaded modules or the unloading of a module. And my removal of the obsolete auto-dev protocol option also eliminated the error message regarding an undetectable protocol and the PreInit error message. The file Xorg.0.log in my installation now looks like this:

The Xorg.0.log file is now cleaner, and I noticed a tiny improvement (I estimate a couple of seconds) in the loading of X Windows when the laptop starts up. Although there has been no change in video and touchpad functionality as far as I can tell, tidying up and removing redundant and incorrect X Windows configuration lines was a worthwhile exercise as I learned something in the process.

You will notice that no keyboard layout and variant are specified in any X Windows configuration file listed above. This laptop has an English (UK) keyboard layout, but sometimes I use it with external USB keyboards having English (UK), English (US), Portuguese (Brazil) and Spanish (Spain) layouts. As the laptop runs KDE, I had already configured KDE to allow me to toggle between the four keyboard layouts and so did not need to configure X Windows for the keyboard layout. However, on machines running Linux with desktop environments that do not have such a facility I add a file with a name such as /etc/X11/xorg.conf.d/15-keyboard.conf containing the following to suit my particular requirements:

Section "InputClass"
        Identifier "keyboard"
        MatchIsKeyboard "yes"
        Option "XkbLayout" "gb,us,br,es"
        Option "XkbVariant" "pc104"
        Option "XkbOptions" "grp:alt_shift_toggle"
EndSection

As the last option suggests, pressing Alt+Shift would toggle between the layouts specified.

Intel HD Audio clicks when a laptop is running on battery power

Yet another audio problem in Linux on my laptop. There were clicks in the audio output from headphones and the built-in speakers while running the laptop on battery power and listening to music. Details of my laptop’s two sound cards are given below:

The Linux kernel has a power-saving feature for Intel HD Audio cards. Each time the audio card goes into the power-saving state, or wakes up from the power-saving state when playing audio, it may produce a clicking noise. Kernel parameter CONFIG_SND_HDA_POWER_SAVE_DEFAULT is used to specify the default time-out in seconds, and setting it to zero disables power-saving mode. Similarly, kernel parameter CONFIG_SND_AC97_POWER_SAVE_DEFAULT is used to specify the default time-out in seconds for AC97 power-saving mode, and setting it to zero disables AC97 power-saving mode. As you can see below, I have both of those parameters set to zero in the kernel:

# grep POWER_SAVE /usr/src/linux/.config
CONFIG_SND_AC97_POWER_SAVE=y
CONFIG_SND_AC97_POWER_SAVE_DEFAULT=0
CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0

Yet I still heard clicks when the laptop was running under battery power. To disable the HD Audio power-save mode for good, I added ‘snd_hda_intel.power_save=0‘ to the end of the kernel boot line in /etc/default/grub and regenerated the grub.cfg file:

# grep GRUB_CMDLINE_LINUX /etc/default/grub
GRUB_CMDLINE_LINUX="BOOT_IMAGE=/kernel-genkernel-x86_64-3.17.1-gentoo-r1 root=/dev/ram0 ramdisk=8192 real_root=/dev/sda6 init=/linuxrc splash=silent,theme:Emergance console=tty1 quiet resume=swap:/dev/sda5 real_resume=/dev/sda5 intel_iommu=off net.ifnames=0 snd_hda_intel.power_save=0"

# mount /dev/sda3 /boot # My boot directory is on its own partition.
# grub2-mkconfig -o /boot/grub/grub.cfg

After rebooting, there are no more clicks when listening to audio under battery power. Problem solved.

Audio in Linux becomes annoying again (continued)

Well, it turned out that the problem playing some system sounds in Thunderbird, described in my previous post, was due to PulseAudio.

Despite sounding fine when played by SMPlayer, the audio clips that sounded distorted/scratchy and too loud when played by Thunderbird also sounded that way when played by VLC. Then I discovered several other .wav files on various Web sites that sounded distorted when played by the browser’s Windows Media Player plug-in (Gecko Media Player). So the problem clearly was not caused by Thunderbird itself. I began to wonder if PulseAudio was the cause. So I adjusted PulseAudio’s sampling frequency, number of fragments and fragment size, and all the clips that previously sounded distorted and too loud now play fine. Here is what I did to fix the problem…

1. Check what PulseAudio is configured to use:

$ pulseaudio --dump-conf
### Read from configuration file: /etc/pulse/daemon.conf ###
daemonize = no
fail = yes
high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 5
allow-module-loading = yes
allow-exit = yes
use-pid-file = yes
system-instance = no
local-server-type = user
cpu-limit = no
enable-shm = yes
flat-volumes = no
lock-memory = no
exit-idle-time = 20
scache-idle-time = 20
dl-search-path = /usr/lib64/pulse-5.0/modules
default-script-file = /etc/pulse/default.pa
load-default-script-file = yes
log-target =
log-level = notice
resample-method = auto
enable-remixing = yes
enable-lfe-remixing = no
default-sample-format = s16le
default-sample-rate = 44100
alternate-sample-rate = 48000
default-sample-channels = 2
default-channel-map = front-left,front-right
default-fragments = 4
default-fragment-size-msec = 25
enable-deferred-volume = yes
deferred-volume-safety-margin-usec = 8000
deferred-volume-extra-delay-usec = 0
shm-size-bytes = 0
log-meta = no
log-time = no
log-backtrace = 0
rlimit-fsize = -1
rlimit-data = -1
rlimit-stack = -1
rlimit-core = -1
rlimit-rss = -1
rlimit-as = -1
rlimit-nproc = -1
rlimit-nofile = 256
rlimit-memlock = -1
rlimit-locks = -1
rlimit-sigpending = -1
rlimit-msgqueue = -1
rlimit-nice = 31
rlimit-rtprio = 9
rlimit-rttime = 1000000
$

2. Check PulseAudio’s output sample rate:

$ pacmd list-sinks | grep sample
sample spec: s16le 2ch 44100Hz
$

So the sample rate is 16 bits @ 44100 Hz and there are 2 output channels (Stereo). My laptop does indeed have two built-in stereo speakers. ‘s16le‘ means ‘signed 16-bit little-endian’.

3. Check PulseAudio’s input sample rate:

$ pacmd list-sources | grep sample
sample spec: s16le 2ch 44100Hz
sample spec: s16le 2ch 44100Hz
$

So the sample rate is 16 bits @ 44100 Hz and there are 2 input channels (Stereo). My laptop does indeed have two built-in microphones. ‘s16le‘ means ‘signed 16-bit little-endian’.

4. Find out the audio card’s maximum sample rate (Hz):

$ arecord -f dat -r 60000 -D hw:0,0 -d 5 test.wav
Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 60000 Hz, Stereo
Warning: rate is not accurate (requested = 60000Hz, got = 48000Hz)
please, try the plug plugin
$

5. As the console output shows that my audio card supports a sample rate of 48000 Hz, edit /etc/pulse/daemon.conf and change the sample rate accordingly:

$ su
Password:
# grep sample-rate /etc/pulse/daemon.conf
; default-sample-rate = 44100
; alternate-sample-rate = 48000
# nano /etc/pulse/daemon.conf
# grep sample-rate /etc/pulse/daemon.conf
default-sample-rate = 48000
; alternate-sample-rate = 48000
# exit
exit
$

6. Find the buffer size and fragment size for each sound card:

$ echo autospawn = no >> ~/.config/pulse/client.conf
$ pulseaudio --kill
$ LANG=C timeout --foreground -k 10 -s kill 10 pulseaudio -vvvv 2>&1 | grep device.buffering -B 10
I: [pulseaudio] sink.c: alsa.driver_name = "snd_hda_intel"
I: [pulseaudio] sink.c: device.bus_path = "pci-0000:00:1b.0"
I: [pulseaudio] sink.c: sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card0"
I: [pulseaudio] sink.c: device.bus = "pci"
I: [pulseaudio] sink.c: device.vendor.id = "8086"
I: [pulseaudio] sink.c: device.vendor.name = "Intel Corporation"
I: [pulseaudio] sink.c: device.product.id = "3b56"
I: [pulseaudio] sink.c: device.product.name = "5 Series/3400 Series Chipset High Definition Audio"
I: [pulseaudio] sink.c: device.form_factor = "internal"
I: [pulseaudio] sink.c: device.string = "front:0"
I: [pulseaudio] sink.c: device.buffering.buffer_size = "19200"
I: [pulseaudio] sink.c: device.buffering.fragment_size = "4800"
--
I: [pulseaudio] source.c: alsa.driver_name = "snd_hda_intel"
I: [pulseaudio] source.c: device.bus_path = "pci-0000:00:1b.0"
I: [pulseaudio] source.c: sysfs.path = "/devices/pci0000:00/0000:00:1b.0/sound/card0"
I: [pulseaudio] source.c: device.bus = "pci"
I: [pulseaudio] source.c: device.vendor.id = "8086"
I: [pulseaudio] source.c: device.vendor.name = "Intel Corporation"
I: [pulseaudio] source.c: device.product.id = "3b56"
I: [pulseaudio] source.c: device.product.name = "5 Series/3400 Series Chipset High Definition Audio"
I: [pulseaudio] source.c: device.form_factor = "internal"
I: [pulseaudio] source.c: device.string = "front:0"
I: [pulseaudio] source.c: device.buffering.buffer_size = "19200"
I: [pulseaudio] source.c: device.buffering.fragment_size = "4800"
$ sed -i '$d' ~/.config/pulse/client.conf # You can just delete the file instead if it didn't exist in the first place.
$

N.B. Depending on your distribution, the PulseAudio file client.conf (if it exists) may be in a different sub-directory of the user’s home directory.

The console output shows that the buffer size was 19200 bits and the fragment size was 4800 bits.

7. Calculate the number of fragments and the fragment size (msec):

default-fragments = 19200 / 4800 = 4

default-fragments-size-msec

= device.buffering.fragment_size [bits] / (sample rate [Hz] x sample width [bits] x number of channels)

= 4800 / ( 48000 x 16 x 2 )

= 0.003125 seconds = 3.125 msec = 3 msec to the nearest integer

8. Edit /etc/pulse/daemon.conf to set these two parameters to the above-mentioned values:

# grep default-fragment /etc/pulse/daemon.conf
; default-fragments = 4
; default-fragment-size-msec = 25
# nano /etc/pulse/daemon.conf
# grep default-fragment /etc/pulse/daemon.conf
default-fragments = 4
default-fragment-size-msec = 3
# exit
exit
$

9. Restart PulseAudio:

$ pulseaudio --kill
$ pulseaudio --start # Only needed if you have 'autospawn = no' in ~/.config/pulse/client.conf
$

10. Check the PulseAudio configuration:

$ pulseaudio --dump-conf
### Read from configuration file: /etc/pulse/daemon.conf ###
daemonize = no
fail = yes
high-priority = yes
nice-level = -11
realtime-scheduling = yes
realtime-priority = 5
allow-module-loading = yes
allow-exit = yes
use-pid-file = yes
system-instance = no
local-server-type = user
cpu-limit = no
enable-shm = yes
flat-volumes = no
lock-memory = no
exit-idle-time = 20
scache-idle-time = 20
dl-search-path = /usr/lib64/pulse-5.0/modules
default-script-file = /etc/pulse/default.pa
load-default-script-file = yes
log-target =

enable-remixing = yes
enable-lfe-remixing = no
default-sample-format = s16le
default-sample-rate = 48000
alternate-sample-rate = 48000
default-sample-channels = 2
default-channel-map = front-left,front-right
default-fragments = 4
default-fragment-size-msec = 3
enable-deferred-volume = yes
deferred-volume-safety-margin-usec = 8000
deferred-volume-extra-delay-usec = 0
shm-size-bytes = 0
log-meta = no
log-time = no
log-backtrace = 0
rlimit-fsize = -1
rlimit-data = -1
rlimit-stack = -1
rlimit-core = -1

rlimit-sigpending = -1
rlimit-msgqueue = -1
rlimit-nice = 31
rlimit-rtprio = 9
rlimit-rttime = 1000000
$

Notice that PulseAudio is now configured to use new values for default-sample-rate, default-fragments and default-fragment-size-msec.

$ echo autospawn = no >> ~/.config/pulse/client.conf
$ pulseaudio --kill
$ LANG=C timeout --foreground -k 10 -s kill 10 pulseaudio -vvvv 2>&1 | grep device.buffering -B 10
I: [pulseaudio] sink.c: alsa.driver_name = "snd_hda_intel"

I: [pulseaudio] sink.c: device.string = "front:0"
I: [pulseaudio] sink.c: device.buffering.buffer_size = "2304"
I: [pulseaudio] sink.c: device.buffering.fragment_size = "576"
--
I: [pulseaudio] source.c: alsa.driver_name = "snd_hda_intel"

I: [pulseaudio] source.c: device.buffering.buffer_size = "2304"
I: [pulseaudio] source.c: device.buffering.fragment_size = "576"
$ rm ~/.config/pulse/client.conf # I didn't have a client.conf to begin with, so I just deleted it.
$ pulseaudio --start
$

Notice that PulseAudio is now using new values for device.buffering.buffer_size and device.buffering.fragment_size.

11. Check PulseAudio’s output sample rate:

$ pacmd list-sinks | grep sample
sample spec: s16le 2ch 48000Hz
$

Notice that PulseAudio is now using a new output sample rate.

12. Check PulseAudio’s input sample rate:

$ pacmd list-sources | grep sample
sample spec: s16le 2ch 48000Hz
sample spec: s16le 2ch 48000Hz
$

Notice that PulseAudio is now using a new input sample rate.

Audio in Linux becomes annoying again

At the moment I seem to be having more audio problems than usual. Last month I blogged about having to fix the ALSA Speaker volume level resetting to zero at boot, and recently two other audio problems have cropped up.

Thunderbird

I have been having trouble with Thunderbird’s ‘system sound’ that announces the arrival of a new e-mail. Lately, Thunderbird has started playing too loud and with significant distortion the audio clip it had been playing perfectly for the last four years. This is especially strange because I created that audio clip with Audacity from another audio clip that sounded too loud when Thunderbird played it. Ironically, the work-around for this latest problem was to switch to the original, much louder sound clip alert.wav instead of the quieter alert_quiet.wav. Not only does Thunderbird now play alert.wav at a lower volume than alert_quiet.wav, but the sound of alert.wav is not distorted when Thunderbird plays it. Yet if I play alert.wav and alert_quiet.wav using SMPlayer, the former is much louder than the latter and neither is distorted. Figure that one out.

The event notification sound that Thunderbird uses to remind me about an impending meeting scheduled in the calendar has now started sounding very distorted too. I still have not found a work-around for that. Event sounds played by the desktop environment I use (KDE) are not distorted, so what is Thunderbird doing? Perhaps the problem is not Thunderbird itself but the audio library it uses, so I need to investigate further.

Skype

Yet another audio problem cropped up this morning when I connected my laptop to an external monitor and keyboard (and thus I left the laptop’s lid almost closed) in an open-plan office and booted the laptop. I entered my username and password on the KDM log-in screen, and the KDE splash screen appeared as usual. After a few seconds the laptop’s speakers suddenly emitted a piercing, continuous howl; the well-known sound of audio feedback from speakers to microphone. It was LOUD. The volume control buttons on the keyboard made no difference, and the sound was so loud that everyone in the office noticed and several people came over to tell me to reset the BIOS (apparently that had fixed the problem for their laptops running Windows).

I kept my finger on the laptop’s power switch and, after several seconds, the laptop powered off. My laptop dual boots Windows 7 and Gentoo Linux, and the audio feedback did not occur when I booted Windows 7. After booting Linux again a couple of times and annoying everyone in the office even more, I discovered I could open the laptop’s lid far enough back to reduce the feedback to a low whine, so I could let KDE finish launching and display the Desktop. I then launched ALSAMixer and discovered that ‘Internal Mic Boost’ was set to 100%. So I immediately lowered it to zero. Then the penny dropped: I had used Skype the previous night without bothering to connect my headphones and external microphone, and Skype had automatically raised ‘Internal Mic Boost’ all the way up to 100%. So I immediately launched Skype, selected ‘Options’ > ‘Sound Devices’ and unticked ‘Allow Skype to automatically adjust my mixer levels’. The next thing I did was add the following lines to the script /etc/local.d/20set_alsa_volume.start mentioned in my previous blog post Fix for ALSA Speaker volume level resetting to zero at boot:

su -c "amixer -c 0 -- sset 'Internal Mic Boost' 0%" -s /bin/sh fitzcarraldo
su -c "amixer -c 0 -- sset 'Internal Mic' 0%" -s /bin/sh fitzcarraldo
su -c "amixer -c 0 -- sset 'Mic Boost' 0%" -s /bin/sh fitzcarraldo
su -c "amixer -c 0 -- sset 'Mic' 0%" -s /bin/sh fitzcarraldo

From now on, only I am allowed to adjust microphone settings! To avoid any possibility of feedback loops in future, the above-mentioned script sets all the microphone channels to zero and I will have to adjust them myself before use. I already have ALSAMixerGUI in the KDE Launcher menu, so it won’t be a big deal to do that.

This fiasco with Skype got me thinking: if Skype is set to automatically adjust mixer levels when you are in a conversation, when you exit Skype why doesn’t it automatically set mixer levels back to the way they were when Skype was launched? It could be done easily and would be more user-friendly than the current way Skype works.

Interrelationship between PulseAudio and ALSA

The final thing I did (yet again) was to adjust all the various ALSA channels and PulseAudio channels to try and get the resulting audio input and output sounding reasonable. This is easier said than done. I often have to mess around with ALSAMixer and PulseAudio Volume Control in order to get audio input and output working satisfactorily in all applications that use audio. It is actually more difficult than it sounds (ouch!) to get ALSA and PulseAudio ‘balanced’ (for want of a better word). In the days before PulseAudio existed, one only had to adjust ALSA. Now, with two agents controlling audio, the task turns out to be surprisingly awkward sometimes.

To sum up, boo to Thunderbird (or whatever it uses to play sounds), boo to Skype and boo to PulseAudio. I’m fed up with audio issues in Linux at the moment. :-x

Update (January 19, 2015): It turns out that the problem in Thunderbird was due to PulseAudio. See my next post for details of how I fixed it.

Updating Intel CPU microcode from Gentoo Linux

Updates to CPU microcode have to be re-applied each time the computer is booted, because the memory updated is volatile (despite the term ‘firmware’ also being used for microcode). Below I describe two methods (there are others) of applying CPU microcode updates in Gentoo Linux. My main laptop has an Intel CPU so I focus here on Intel microcode updates. The procedure is almost the same for AMD CPUs, but the AMD CPU binary update file (‘binary blob’) is installed by the sys-kernel/linux-firmware package.

METHOD 1: Use an initscript in the boot runlevel with a kernel module

Until recently I was using an initscript named microcode_ctl, which uses a program (also named microcode_ctl) and a kernel module (microcode.ko) to update the Intel CPU microcode during boot. This was straightforward to set up in Gentoo Linux:

1. Build the kernel with CONFIG_MICROCODE=m and CONFIG_MICROCODE_INTEL=y.

This is what I configured in the kernel:

# grep -i microcode /usr/src/linux/.config
CONFIG_MICROCODE=m
CONFIG_MICROCODE_INTEL=y
# CONFIG_MICROCODE_AMD is not set
CONFIG_MICROCODE_OLD_INTERFACE=y
# CONFIG_MICROCODE_INTEL_EARLY is not set
# CONFIG_MICROCODE_AMD_EARLY is not set

2. Install two packages and add an OpenRC initscript to the boot runlevel:

# emerge microcode-data microcode-ctl
# rc-update add microcode_ctl boot

The initscript will re-update the CPU microcode every time the computer is rebooted.

Installing the package microcode-data downloads a compressed file (microcode-yyyymmdd.tgz) from the Intel Download Centre, extracts a text file named microcode.dat and parses the text in it to create a set of binary ‘blobs’ in the directory /lib/firmware/intel-ucode/ (one blob for each model of Intel CPU).

Before rebooting, check the revision of microcode in the CPU (the microcode revision is shown for each logical core):

# This is for the Core i7-720QM CPU in my Compal NBLB2 laptop.
# grep microcode /proc/cpuinfo
microcode : 0x3
microcode : 0x3
microcode : 0x3
microcode : 0x3
microcode : 0x3
microcode : 0x3
microcode : 0x3
microcode : 0x3

If I use this method of updating the microcode, the initscript runs after the message ‘Waiting for uevents to be processed ...‘ is displayed on VT1 while booting. After the module has performed the update, the microcode revision in the CPU’s logical cores has changed:

# grep microcode /proc/cpuinfo
microcode : 0x7
microcode : 0x7
microcode : 0x7
microcode : 0x7
microcode : 0x7
microcode : 0x7
microcode : 0x7
microcode : 0x7

[ 15.840997] microcode: Microcode Update Driver: v2.00 , Peter Oruba

Notice that the microcode update occurred in the period from 15.749533 to 15.840997 seconds after the kernel started running, and the microcode was updated from revision 0x3 to 0x7.

METHOD 2: Use the kernel’s built-in Early Update driver

Although the initscript method works perfectly in my case and the update is complete by the time the laptop has finished booting, I wanted to update the CPU microcode earlier. Updating microcode early can fix CPU issues before they occur during kernel boot time. It is possible to configure the kernel to update microcode early by setting CONFIG_MICROCODE_EARLY and CONFIG_MICROCODE_INTEL_EARLY in the kernel. See /usr/src/linux/Documentation/x86/early-microcode.txt for details. That document only refers to initrd files, but, in fact, it also applies to initramfs files.

The Early Update kernel driver will align misaligned microcode data (see Notes on Intel Microcode Updates and [PATCH 7/8] x86, microcode, intel: guard against misaligned microcode data), but you can pre-align the data yourself if you wish by using a .padding file as explained on the latter page. However I did not bother doing that; I leave the Early Update kernel driver to take care of aligning the microcode, as the time penalty to align it is small compared to the overall update time.

It is possible to download the latest compressed Intel microcode data file yourself from the Intel Download Centre. The latest file released is microcode-20140913.tgz at the time of writing. It contains only a text file named microcode.dat, not the required binary blob. Actually, microcode.dat contains data in text format for several Intel CPU models. The microcode.dat file should reside in the directory /lib/firmware/. In the case of Gentoo it is a waste of time manually obtaining the microcode.dat file this way, as there is no tool in Gentoo specifically for creating a binary blob from the microcode.dat file. Therefore just install the Gentoo package sys-apps/microcode-data (which you would have done in any case if you were using the microcode_ctl initscript to load the microcode update to the CPU) and it will automatically download the compressed file from the Intel Web site, unpack it, copy the file microcode.dat to /lib/firmware/ and create the binary blobs in the directory /lib/firmware/intel-ucode/.

You may have read of a tool named intel-microcode2ucode used in other Linux distributions. Gentoo does not build intel-microcode2ucode (the source code of which is included in the Gentoo package sys-apps/microcode-data) as a stand-alone tool, but the act of installing microcode-data creates the required binary files in /lib/firmware/intel-ucode/. i.e. the following command does the complete job:

# emerge microcode-data

I looked in /proc/cpuinfo to confirm the model of CPU in my laptop:

$ grep model /proc/cpuinfo
model : 30
model name : Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz
model : 30
model name : Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz
model : 30
model name : Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz

model name : Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz
model : 30
model name : Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz

I was able to find the CPUID and other data for that model from the Web site CPU World:

CPUID 106E5
Family 6 (06 hex)
Model 30 (1E hex)
Stepping 5 (05 hex)

Therefore the file /lib/firmware/intel-ucode/06-1e-05 (Family-Model-Stepping in hexadecimal) is the binary blob for my specific CPU model.

First I used genkernel to rebuild the current kernel with CONFIG_MICROCODE_EARLY=y and CONFIG_MICROCODE_INTEL_EARLY=y.

# mount /dev/sda3 /boot # /boot is on a separate partition in my installation.

# Backup the files of the existing kernel image and initramfs:
# cp /boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1 /home/fitzcarraldo/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.bak
# cp /boot/kernel-genkernel-x86_64-3.17.1-gentoo-r1 /home/fitzcarraldo/kernel-genkernel-x86_64-3.17.1-gentoo-r1.bak
# cp /boot/System.map-genkernel-x86_64-3.17.1-gentoo-r1 /boot/fitzcarraldo/System.map-genkernel-x86_64-3.17.1-gentoo-r1.bak

# Now rebuild the kernel:
# zcat /proc/config.gz > /usr/src/config
# genkernel --kernel-config=/usr/src/config --menuconfig --splash=Emergance --disklabel all # Set CONFIG_MICROCODE_EARLY and CONFIG_MICROCODE_INTEL_EARLY.
# emerge @module-rebuild
# grub2-mkconfig -o /boot/grub/grub.cfg

This is what I have after rebuilding the kernel:

# grep -i microcode /usr/src/linux/.config
CONFIG_MICROCODE=y
CONFIG_MICROCODE_INTEL=y
# CONFIG_MICROCODE_AMD is not set
CONFIG_MICROCODE_OLD_INTERFACE=y
CONFIG_MICROCODE_INTEL_EARLY=y
# CONFIG_MICROCODE_AMD_EARLY is not set
CONFIG_MICROCODE_EARLY=y

Then I prepended the cpio file containing the binary blob to the initramfs file (see the instructions in /usr/src/linux/Documentation/x86/early-microcode.txt):

# mkdir -p /boot/initrd/kernel/x86/microcode
# cd /boot/initrd
# cp /lib/firmware/intel-ucode/06-1e-05 kernel/x86/microcode/GenuineIntel.bin
# find . | cpio -o -H newc >../ucode.cpio
# cd ..
# cp /boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1 /home/fitzcarraldo/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.bak.early # Backup the recently-built initramfs first.
# cat ucode.cpio /boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1 >/boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.ucode
# cp /boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.ucode /boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1
# rm /boot/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.ucode
# umount /boot
# rc-update del microcode_ctl boot # Disable the initscript so that microcode.ko will no longer be used when I reboot.

Reboot.

Use the following commands to check if the CPU microcode has been updated:

# grep microcode /proc/cpuinfo
# dmesg | grep microcode

There is no point looking in /var/log/messages, because syslog-ng has not started running when the early microcode update occurs.

# grep microcode /proc/cpuinfo
microcode : 0x7
microcode : 0x7
microcode : 0x7

Compare the update time in the dmesg output above with the update time in the dmesg output for an update done using the initscript (Method 1, further up). With the Early Update driver, the update was complete in 0.278696 seconds. With the initscript and kernel module, the update was complete in 15.840911 seconds. Quite a difference.

I do not know why the dmesg output does not have a message for Core 0 in the group of messages before 1.000000 second elapsed. The message at 1.888471 shows it was updated, so I assume the kernel ring buffer was not large enough and the message was overwritten. Cores 1, 2 and 3 were updated in the period between 0.252234 and 0.278696 seconds, and then all eight logical cores are listed in the period between 1.888471 and 1.888597 seconds. I’m not sure of the precise messages expected, but they look similar to the results obtained by users in other distributions, such as the following CrunchBang Linux output:

$ cat /proc/cpuinfo | grep microcode | uniq
microcode : 0x19

Finally, I deleted the temporary work directory and files:

# mount /dev/sda3 /boot
# rm -rf /boot/initrd/
# rm /boot/ucode.cpio
# rm /home/fitzcarraldo/kernel-genkernel-x86_64-3.17.1-gentoo-r1.bak
# rm /home/fitzcarraldo/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.bak
# rm /home/fitzcarraldo/System.map-genkernel-x86_64-3.17.1-gentoo-r1.bak

# Optional. Could keep the following file in case Intel issues a new microcode.dat file and I want to create a new concatenated initramfs file:
# rm /home/fitzcarraldo/initramfs-genkernel-x86_64-3.17.1-gentoo-r1.bak.early

Of course, you will need to repeat the whole process and create a new concatenated initramfs file in any of the following cases:

a) you build a new version of the kernel;

b) you rebuild the current version of the kernel with different configuration settings;

c) Intel releases a new version of the microcode (which does not happen often).

It seems the Early Update driver still has some bugs, so I expect the message output to change in future kernel releases. See e.g. [PATCH 0/8] x86, microcode, intel: fixes and enhancements, [PATCH 3/8] x86, microcode, intel: clarify log messages, Re: [PATCH 3/8] x86, microcode, intel: clarify log messages and a bunch of other very recent posts in the kernel mailing list regarding the Early Update driver and CPU microcode updates.

Laptop Mode Tools revisited due to a change in its functionality

The site statistics for this blog can be quite revealing. For example, over the last two or three months I noticed that my post How to prevent a USB mouse auto-suspending in Linux when a laptop’s power supply is disconnected has consistently been one of the most viewed. Given the problems I experienced with Laptop Mode Tools 1.65 (see my Gentoo Linux Forums post Bug in laptop-mode-tools-1.65? and Gentoo Linux Bugzilla Bug Report No. 520124), I was not entirely surprised. Thanks to fellow Gentoo Linux and Laptop Mode Tools user Ted Tanberry I learned that Version 1.65 had stopped using Laptop Mode Tools module usb-autosuspend, and started using Laptop Mode Tools module runtime-pm instead. At least that was the developer’s intention, but he had not implemented it correctly. The aforementioned Gentoo Linux bug report explains in detail the problem with Version 1.65.

The situation in my Gentoo Linux installation with laptop-mode-tools-1.64 installed, providing the functionality I desired, was as follows:

a. The precise package installed:

# eix -I laptop-mode-tools
[U] app-laptop/laptop-mode-tools
Available versions: 1.64 (~)1.65 (~)1.65-r1 (~)1.66 {+acpi apm bluetooth scsi}
Installed versions: 1.64(10:04:43 21/10/14)(acpi bluetooth -apm -scsi)
Homepage: http://www.samwel.tk/laptop_mode/
Description: Linux kernel laptop_mode user-space utilities

b. The auto-suspend state when the laptop PSU was connected:

# for d in /sys/bus/usb/devices/[0-9]* ; do if [[ -e $d/product ]] ; then echo -e "`basename $d`\t`cat $d/power/control`\t`cat $d/speed`\t`cat $d/product`" ; fi ; done
1-1.2 on 1.5 USB Laser Mouse
2-1.2 on 12 Fingerprint Sensor
2-1.3 on 480 USB 2.0 Camera

c. The contents of the file /lib64/udev/rules.d/99-laptop-mode.rules:

ACTION=="change", SUBSYSTEM=="power_supply", RUN+="lmt-udev auto"
ACTION=="add|remove", SUBSYSTEM=="machinecheck", RUN+="lmt-udev auto"
ACTION=="add|remove", SUBSYSTEM=="usb", RUN+="lmt-udev force modules=usb-autosuspend devices=%k"

d. The contents of file /etc/laptop-mode/conf.d/usb-autosuspend.conf:

Having experienced the problems with the buggy Laptop Mode Tools 1.65, I re-installed 1.64 and had been using that successfully until a week ago. Then I noticed that 1.66 had been released, so I installed it:

# emerge laptop-mode-tools
.
.
.
>>> Installing (1 of 1) app-laptop/laptop-mode-tools-1.66::gentoo
* To enable automatic power state event handling,
* e.g. enabling laptop_mode after unplugging the battery,
* both laptop_mode and the acpid daemon must be
* added to default runlevel:
* # rc-update add laptop_mode default
>>> Auto-cleaning packages...

>>> No outdated packages were found on your system.

* GNU info directory index is up-to-date.

I would not have expected that ewarn message about adding laptop_mode to the default runlevel, as the ebuild is only supposed to display the warning if laptop_mode is not assigned to the default runlevel. But, sure enough, something had removed it:

# rc-update show -v | grep laptop
laptop_mode |
# rc-update show -v | grep acpi
acpid |      default

I don’t know what removed laptop_mode from the default runlevel. It was certainly assigned previously, as proved by Laptop Mode Tools 1.64 working as expected when I connected and disconnected the laptop’s PSU from the mains (see my earlier post). Anyway, I re-added it:

# rc-update add laptop_mode default
* service laptop_mode added to runlevel default

If you use systemd instead of OpenRC, instead of adding laptop_mode to the default runlevel you would need to use the following command:

# systemctl enable laptop_mode.service

Notice that the incorrect contents of 99-laptop-mode.rules and /etc/laptop-mode/laptop-mode.conf that were present in Laptop Mode Tools 1.65 have been fixed in 1.66:

# cat /lib64/udev/rules.d/99-laptop-mode.rules
ACTION=="change", SUBSYSTEM=="power_supply", RUN+="lmt-udev auto"
ACTION=="add|remove", SUBSYSTEM=="machinecheck", RUN+="lmt-udev auto force"
ACTION=="add|remove", SUBSYSTEM=="usb", RUN+="lmt-udev force modules=runtime-pm devices=%k"

# cat /etc/laptop-mode/laptop-mode.conf | grep usb-autosuspend
#

The ebuild for Laptop Mode Tools 1.66 did not delete the now-redundant file /etc/laptop-mode/conf.d/usb-autosuspend.conf but it is presumably ignored by 1.66 anyway.

From now on I must configure the contents of /etc/laptop-mode/conf.d/runtime-pm.conf instead. After installing Laptop Mode Tools 1.66 it contained the following:

#
# Configuration file for Laptop Mode Tools module runtime-pm
#
# For more information, consult the laptop-mode.conf(8) manual page.

So, in order to stop my laptop’s USB mouse, USB external keyboard and some internal USB devices from going to sleep when my laptop is only on battery power, I made the following change to a line in /etc/laptop-mode/conf.d/runtime-pm.conf:

# External keyboard at one office, internal Webcam, internal fingerprint sensor, Logitek NX50 notebook mouse
AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST="03f0:0024 064e:a115 147e:1001 046d:c052"

My earlier post about Laptop Mode Tools explained one method for finding the device ID for each USB device, but the lsusb command can also be used:

# lsusb
Bus 002 Device 005: ID 03f0:0024 Hewlett-Packard KU-0316 Keyboard <---- External keyboard at one office
Bus 002 Device 004: ID 064e:a115 Suyin Corp. <---- Built-in Webcam

Bus 001 Device 002: ID 8087:0020 Intel Corp. Integrated Rate Matching Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Although the Laptop Mode Tools usb-autosuspend module is supposed to be unused in 1.66, I edited /etc/laptop-mode/conf.d/usb-autosuspend.conf (which was not deleted by the 1.66 ebuild) and changed CONTROL_USB_AUTOSUSPEND="auto" to CONTROL_USB_AUTOSUSPEND="0" just to be on the safe side.
