Using GeckoLinux to resurrect my old nettop

Background/History

Back in early 2010, when nettops were the latest thing, I bought an ASRock ION 330HT nettop, billed as an ‘HTPC‘ (Home Theatre PC):

  • CPU: Intel Atom 330 1.6GHz (Dual core)
  • Memory: Supports DDR2 800MHz, 2 x SO-DIMM slots, default 2GB (2 x 1GB), maximum up to 4GB (due to the CPU limitation, the actual memory size available to the OS may be less than 4GB).
  • Chipset: NVIDIA ION graphics processor
  • Graphics: NVIDIA ION Graphics, supports DX10 / HD 1080p playback
  • Audio: 7.1 CH HD Audio with DTS
  • HDD: 320GB 2.5″ HDD, capable of supporting RAID 0 and 1 by adopting a second 2.5″ HDD
  • ODD: DVD Super Multi
  • LAN: Gigabit Ethernet
  • WLAN: 802.11b/g/n Wi-Fi
  • Rear I/O: 1 x HDMI, 1 x D-Sub VGA, 6 x USB 2.0, 1 x S/PDIF, 1 x powered eSATA/USB (For powered eSATA function, Hot Plug function is supported in RAID / AHCI mode only. IDE mode does not support Hot Plug function.)
  • Remote Controller: MCE remote controller
  • External Power Unit: 65W/19V adapter
  • Firmware: PC BIOS (no UEFI)

In 2010 so-called smart TVs were not really that smart. I still had a large Sony Trinitron TV with a CRT, and I wanted to see if I could use the nettop with it. I bought a DVB-T USB adapter to enable the nettop to access digital terrestrial television, and I installed XBMC (now called KODI). I installed the now-defunct Sabayon Linux, and had a hell of a job getting ASRock’s CIR [Windows] MCE (Media Center Edition) remote to work. ASRock only released a driver (lirc_wb677) for the Nuvoton w836x7hg CIR chip in the nettop for Ubuntu 9.10, 10.04 and 10.10, and I had to patch it to get it to work with LIRC in Sabayon Linux. Later that year developer Jarrod Wilson released the first version of a new driver named nuvoton-cir for the Nuvoton w836x7hg chip, and in 2011 I had another struggle to get that working with LIRC and XBMC in Sabayon Linux.

To be able to use the DVB-T USB adapter I installed Tvheadend in Sabayon Linux, which worked well, although the adapter needed to be connected to the house TV aerial in order to provide good reception, i.e. the small indoor aerial supplied with the DVB-T adapter was next to useless.

I bought a VGA-to-Composite Video converter to connect the nettop’s D-Sub VGA socket to the TV’s composite video input. The Linux Desktop displayed on the CRT TV screen was OK-ish but, as you would expect, not comparable to the display on a TFT monitor.

Basically, I was not satisfied with the result, and the nettop went back into its box after very little use. I did get it out briefly in 2016 to upgrade the 2GB RAM (two 1GB modules) to the maximum allowable 4GB (two 2GB modules) in case I might want to use the nettop in future. With two 2GB RAM modules the nettop detects 3327MB of RAM, which limits what can be done with it.

When ‘proper’ smart TVs came onto the market, there was no longer any incentive to use an HTPC; everything and more that a nettop HTPC did could be done by a smart TV. In 2015 I succumbed and bought an LG smart TV, added a USB 1TB HDD, connected my DVD player to the TV and forgot about the nettop. The LG TV developed a fault three years later. I fixed it but its lack of catch-up TV apps for some of the main TV stations became irritating so, three years ago, I bought a new TV. The media player on the TV (a FINLUX TV) cannot play FLAC music files, and the Web browser is very slow with a buggy UI, so I began thinking about resurrecting the ASRock nettop in order to be able to browse the Web properly on my TV and to play my music flles through the TV’s sound bar. I finally got around to doing this recently, so here is the story…
 
 
Connections

I have a Rii i8 mini wireless keyboard which I used with my smart TV, so I connected its lead with USB wireless receiver pigtail and micro-USB charging plug pigtail to one of the USB ports on the back of the nettop. The lead is long enough to enable the USB wireless receiver (about the size of a USB Type A plug) to sit between the sound bar and the TV stand. The micro-USB charging plug pigtail lies out of sight on the TV stand behind the sound bar, ready to charge the mini keyboard when needed. Excellent wireless mini keyboard with touchpad, by the way.

The nettop is connected to the TV by an HDMI cable. The sound bar is connected to the TV by a 3.5mm jack plug cable, and connected to the nettop by an S/PDIF (optical) cable. I use the sound bar’s remote to switch easily between TV audio and nettop audio.
 
 
Finding a suitable Linux distribution

Given the limitations of the nettop’s CPU and memory, I wanted to install a distribution with a lightweight Desktop Environment. I like LXQt, so that would have been my choice if possible. Gentoo Linux is installed on my laptops, and Lubuntu 21.04 on my family’s desktop. LXQt is available for Gentoo Linux but I would not dream of installing Gentoo Linux on a relatively slow nettop with less than 4GB accessible, but Lubuntu seemed a good candidate. Therefore I created a Live USB pendrive with Lubuntu 21.10, which booted fine on all my other machines (including a legacy machine with PC BIOS only, not UEFI) but would not boot on the ASRock nettop. It would get as far as the GRUB menu then stall. So I tried Mageia (the Xfce release, as there is no Live LXQt release), but the result was similar. So then I tried PCLinuxOS (also the Xfce release, as there is no Live LXQt release), and that did install and run nicely (although the edges of the file manager’s windows were thick dashed lines). Everything worked well until I selected Suspend and tried to Resume, which resulted in the following messages on the screen and the nettop hung:

[ 1774.594461] IRQ 26: no longer affine to CPU1
[ 1774.602213] IRQ 16: no longer affine to CPU3
[ 1774.602227] IRQ 18: no longer affine to CPU3
[ 1774.613499] TSC synchronization [CPU#0 -> CPU#1]:
[ 1774.613504] Measured 377387956 cycles TSC warp between CPUs, turning off TSC clock.
[ 1774.613552] TSC found unstable after boot, most likely due to broken BIOS. Use 'tsc=unstable'.
[ 1774.609000] clocksource: Checking clocksource tsc synchronization from CPU 1 to CPUs 0.
[ 1774.609000] clocksource:         CPUs 0 ahead of CPU 1 for clocksource tsc.
[ 1774.609000] clocksource:         CPU 1 check durations 6592ns - 6592ns for clocksource tsc.
_

I could get rid of the clock-related messages by adding ‘tsc=unstable‘ to the kernel boot line in /boot/grub/grub.cfg, but I could not get rid of the ‘no longer affine’ messages and the hanging every time the nettop resumed from suspension. I wondered if the BIOS was to blame, so I downloaded onto a FAT32-formatted USB pendrive the latest version (1.2) of the 330HT BIOS from the ASRock Web site and installed it on the nettop (easy: press F6 at boot), but the problem remained. I began to wonder it any modern Linux release would work on this nettop.

So it was time to try another distribution. My searches on DistroWatch showed that GeckoLinux (“a Linux spin based on the openSUSE distribution, with a focus on polish and out-of-the-box usability on the desktop” according to its Web site) has static and rolling editions based on openSUSE Leap and openSUSE Tumbleweed respectively, and has many Desktop Environment releases, including LXQt. The availability of LXQt attracted my attention, but I was also curious to try openSUSE and the Btrfs file system. I did try openSUSE briefly many years ago (possibly more than a decade), but I have never used Btrfs. So I decided it was worth a shot.

I downloaded the latest available ISO for GeckoLinux ROLLING LXQt and used dd on one of my Linux machines to create a bootable USB pendrive:

user $ sudo blkid # Find out which device is the pen drive
user $ sudo dd if=/home/fitzcarraldo/Downloads/GeckoLinux_ROLLING_LXQt.x86_64-999.220105.0.iso of=/dev/sdd bs=4M status=progress && sync

I booted the pendrive on the nettop and launched the GeckoLinux installer, which had no trouble installing the OS on the nettop’s HDD. Further on I point out a couple of minor niggles I found with the application menu but, by and large, I find GeckoLinux Rolling LXQt provides a good, polished user interface and experience.
 
 
Setting up auto login and disabling a lock screen

I found that, in order to get auto login working correctly in the installation, I needed to specify a user password during installation and then set up auto login after booting into the new installation:

‘Application Menu’ > ‘Preferences’ > ‘YaST User and Group Management’

  1. Select the user and click on ‘Expert Options’
  2. Select ‘Login Settings’
  3. Tick ‘Auto Login’
  4. Tick ‘Passwordless Logins’

One needs to be a little careful not to end up with both light-locker and XScreenSaver providing lock screens. I wanted only a screensaver and no locking of the user session after a period of inactivity. Any press of a key or tap of the touchpad on my Rii i8 mini wireless keyboard will simply stop the screensaver animation and then display the Desktop.

‘Application Menu’ > ‘Preferences’ > ‘LXQt Settings’ > ‘Session Settings’

  1. In ‘Basic Settings’, untick ‘Lock screen before suspending/hibernating’.
  2. In ‘Autostart’, ‘XScreenSaver’ under ‘LXQt Autostart’ needs to be ticked.

‘Application Menu’ > ‘Preferences’ > ‘Screensaver’

If a window appears informing you that the XScreenSaver daemon is not running and offering to launch it, click ‘OK’.

  1. Select ‘Mode: Only One Screen Saver’.
  2. Select a screensaver animation (I use ‘GL Matrix’).

‘Application Menu’ > ‘System Tools’ > ‘dconf Editor’

Configure the following settings for light-locker:

idle-hint false
late-locking false
lock-after-screensaver 0
lock-on-lid false
lock-on-suspend false

‘Application Menu’ > ‘Preferences’ > ‘LXQt Settings’ > ‘Power Management’

Untick ‘Enable Battery Watcher’, ‘Enable Lid Watcher’ and ‘Enable Idleness Watcher’ on the respective tabs.
 
 
Setting the hostname

I set a static hostname (I opted for ‘ion330ht’) by selecting ‘Application Menu’ > ‘Preferences’ > ‘YaST Network’ and entering the hostname on the ‘Hostname/DNS’ tab.
 
 
Package Management

Both the YaST Software Management GUI and the zypper command are new to me, so I still have a lot to learn.

The main package repositories were already added, but to learn how to add other repositories manually see the following articles:

Anyway, these are the repositories currently in use on this nettop:

ion330ht:/home/fitzcarraldo # zypper repos
Repository priorities in effect:                                      (See 'zypper lr -P' for details)
      90 (raised priority)  :  1 repository
      97 (raised priority)  :  1 repository
      98 (raised priority)  :  2 repositories
      99 (default priority) :  4 repositories
     115 (lowered priority) :  4 repositories

Repositories 8 to 11 in the above list were added when I used ‘1 Cick Install’ on an openSUSE Software Web page for a specific package.

Most of what I needed was already installed, and I installed a few other packages using either the YaST Software Management GUI, the zypper command or ‘1 Click Install’:

● To be able to use the locate command to search for specific files:

   mlocate

● To be able to configure the LXQt Keyboard State Indicator on the Panel to display the flag of the keyboard language:

   iso-country-flags-png

● I was not sure if online updates would be advisable, but it looked potentially useful:

   yast2-online-update-configuration

● Some Web sites are not displayed correctly in Firefox, and I use Google’s Chrome browser for those:

   google-chrome-stable

● The Clementine music player (already installed) has the ability to display visualisations using projectM:

   projectM
   projectM-data

However, I could not get projectM to load its visualisation files, but I need to tinker more with it.

● I wanted to implement my scheme to scan automatically any files downloaded into the ~/Downloads/ directory (see my 2017 post), so I installed the following packages:

   clamav
   kdialog
   inotify-tools
   acl

(See further down for the addtional steps I took in order to get my scheme to work in GeckoLinux/openSUSE.)

● A GUI front-end to ClamAV in case I wanted to scan any files or directories manually:

   clamtk

● Although not essential, I installed the package monitoring-plugins-clamav in case I wanted to use it to check if the virus signatures are current, although my Bash script in a 2021 post serves the same purpose.

● To provide the commands dig, host and nslookup in case I need them in future:

   bind-utils

● To provide the man command and pages from the Linux Documentation Project:

   man-pages
   man

● To enable me to specify the window colour and size etc. in xterm, if I wish:

   xtermset

● To provide a GUI utility to show the amount of used and unused space in each partition:

   filelight

● Various multimedia codecs were already installed, but I had to install the package libdvdcss2 in order to be able to play commercial DVDs, as VLC would not play them. I installed it by using ‘1 Click Install’:

https://software.opensuse.org/package/libdvdcss2

● I use Signal Messenger, so I installed the package signal-messenger by using ‘1 Click Install’:

https://software.opensuse.org/package/signal-desktop

However, a subsequent rolling update flagged a dependency conflict requiring it to be uninstalled.

● To enable machines running Windows to browse SMB shares in File Explorer I installed the WS-Discovery daemon:

   wsdd

● To be able to edit tags in my music files:

   kid3-qt

● To be able to copy characters not available on the keyboard:

   kcharselect

● To install ir-keytable, *.toml files and 70-infrared.rules so that I could try to get the ASRock CIR MCE remote working using the in-kernel support for IR decoders, instead of LIRC:

   v4l-utils

● I no longer use KODI but I wanted to see if I could get the ASRock CIR MCE remote to control it using the in-kernel support for IR decoders instead of LIRC:

   kodi

● I prefer SMPlayer to VLC (which came installed in GeckoLinux Rolling LXQt):

   smplayer

● To be able to edit .mkv files, e.g. to change the default audio language etc.:

   mkvtoolnix
   mkvtoolnix-gui
 
 
Web Service Discovery host daemon (wsdd)

Having installed the package wsdd by using ‘Preferences’ > ‘YaST Software Management’ I performed the following steps as root user:

ion330ht:/home/fitzcarraldo # systemctl enable wsdd

I edited /etc/systemd/system/multi-user.target.wants/wsdd.service and added ‘--workgroup=HOME‘ to the ExecStart line, as my Windows workgroup is HOME rather than WORKGROUP:

ExecStart=/usr/sbin/wsdd --shortlog --workgroup=HOME -c /run/wsdd $WSDD_ARGS

ion330ht:/home/fitzcarraldo # systemctl daemon-reload
ion330ht:/home/fitzcarraldo # systemctl start wsdd

Although not necessary (and nothing to do with wsdd on the nettop), I performed the steps given in my 2020 blog post ‘A Linux command-line utility to discover and list WSD-enabled computers and printers on a home network‘. Works a treat.
 
 
SMB

This SMB configuration is for my home network that uses Broadcast NetBIOS Name Resolution, SMB and WS-Discovery. See the following posts (and all the comments on each, some of which contain important updates) for an explanation of how I set these up, making it relatively straightforward to add a device that uses the SMB protocol and enable it to browse shares on the other machines, and vice versa.

Note also that the smb, nmb and wsdd services must be running (see the next section).

I used the command ‘ip address‘ to find out the names of the wired and wireless interfaces, then I edited the file /etc/samba/smb.conf to contain the following (the Workgroup name in my home network is ‘HOME’ rather than the usual default of ‘WORKGROUP’):

[global]
;no need to specify 'smb ports' as ports 139 & 445 used by default
workgroup = HOME
netbios name = ion330ht
case sensitive = no
browseable = yes

;If this machine becomes a Master Browser, the following parameter allows it to hold the browse list
browse list = yes

printcap name = cups
printing = cups

log file = /var/log/samba/log.%m
max log size = 50

security = user
map to guest = bad user

encrypt passwords = yes
passdb backend = tdbsam

domain master = no
local master = yes
preferred master = yes
name resolve order = bcast
dns proxy = no

;Listen for NetBIOS on Ethernet and Wireless interfaces
;Names of the interfaces found using ifconfig command
interfaces = enp0s10 wlp2s0
server string = Samba Server on ion330ht
log level = 2

[netlogon]
comment = Network Logon Service
path = /var/lib/samba/netlogon
guest ok = yes

[printers]
comment = All Printers
path = /var/spool/samba
guest ok = yes
printable = yes
create mask = 0700

[print$]
path = /var/lib/samba/printers
write list = @adm root
guest ok = yes

[fitzcarraldo]
path = /home/fitzcarraldo/Public-fitzcarraldo
comment = To pass files to and from ion330ht
browseable = yes
public = yes
writable = yes
valid users = fitzcarraldo

I used the command ‘smbpasswd -a fitzcarraldo‘ to specify my SMB password, which has to be the same as my Linux password.
 
 
Starting Services

‘Application Menu’ > ‘Preferences’ > ‘YaST Services Manager’

In addition to any services already configured to start ‘On Boot’, make sure the following are set to start ‘On Boot’:

  • clamd
  • cups
  • nmb
  • ntpd
  • smb
  • wsdd

 
 
User’s Locale

Even though I had configured during installation (and confirmed after installation using YaST) the language, keyboard language and location as British English and Europe/London respectively, the dates of files displayed by PCManFM-Qt were still in US format. I added the following lines to the file ~/.profile to fix that:

export LANG="en_GB.UTF-8"
export LC_CTYPE="en_GB.UTF-8"
export LC_NUMERIC="en_GB.UTF-8"
export LC_TIME="en_GB.UTF-8"
export LC_COLLATE="en_GB.UTF-8"
export LC_MONETARY="en_GB.UTF-8"
export LC_MESSAGES="en_GB.UTF-8"
export LC_PAPER="en_GB.UTF-8"
export LC_NAME="en_GB.UTF-8"
export LC_ADDRESS="en_GB.UTF-8"
export LC_TELEPHONE="en_GB.UTF-8"
export LC_MEASUREMENT="en_GB.UTF-8"
export LC_IDENTIFICATION="en_GB.UTF-8"
export LC_ALL=""

Susequently I discovered that the file /etc/sysconfig/language contains variables that I probably could have edited manually to achieve the same thing for users’ accounts.
 
 
GUI Appearance

As I am sitting on a sofa viewing the TV screen from a distance, text and icons have to be larger than on a normal desktop or laptop machine. This was easy enough to configure.

I right-clicked on the LXQt Panel and selected ‘Configure Panel’ to increase the height of the Panel and the size of the Panel icons and Panel font. I selected ‘Preferences’ > ‘LXQt Settings’ > ‘Appearance’ to increase the size of the icons and font in the rest of the UI, to change the icon theme to Oxygen, and to change the mouse cursor size to 50. I selected ‘Preferences’ > ‘LXQt Settings’ > ‘Desktop’ (or right-click on the Desktop and select ‘Desktop Preferences’) to increase the icon size and font size on the Desktop.

I increased the font size of the Firefox address bar, bookmarks toolbar, tabs and page using the two methods (devp and userChrome.css) described on the following Mozilla Support page: Text size of menus and tool bars way too small. I want to be able to increase the size.

ClamAV virus signatures database was not being updated

The ClamAV signatures database was not being updated automatically after I installed ClamAV, so I needed to fix that.

Using the following commands listed on the openSUSE Wiki page for ClamAV did not work, because there is no freshclam.service file:

fitzcarraldo@ion330ht:~> sudo systemctl start freshclam
fitzcarraldo@ion330ht:~> sudo systemctl enable freshclam

I suspected that GeckoLinux/openSUSE Tumbleweed uses systemd timers instead of cron, and indeed I found a timer file for freshclam:

fitzcarraldo@ion330ht:~> locate timer | grep fresh
/usr/lib/systemd/system/freshclam.timer
fitzcarraldo@ion330ht:~> cat /usr/lib/systemd/system/freshclam.timer
[Unit]
Description=Timer for freshclam virus definitions downloader

[Timer]
OnBootSec=5m
OnUnitActiveSec=2h
Persistent=true

[Install]
WantedBy=timers.target

I enabled it as follows:

fitzcarraldo@ion330ht:~> sudo systemctl enable freshclam.timer
[sudo] password for root: 
Created symlink /etc/systemd/system/timers.target.wants/freshclam.timer → /usr/lib/systemd/system/freshclam.timer.
fitzcarraldo@ion330ht:~> sudo systemctl start freshclam.timer
fitzcarraldo@ion330ht:~> sudo systemctl is-active freshclam.timer
active

systemd now runs freshclam 5 minutes after the machine boots and every 2 hours thereafter.
 
 
Automatic scanning for viruses in the Downloads directory

See my 2017 blog post Using the ClamAV daemon to scan files placed in my Downloads directory in Gentoo Linux, which I have implemented successfully on machines running Gentoo Linux and Lubuntu. However, in GeckoLinux it took a bit more effort to get the scheme working.

GeckoLinux Rolling (and, I assume, also openSUSE Tumbleweed) allocates clamav to a user named ‘vscan‘ and a group named ‘vscan‘ instead of a user named ‘clamav‘ and a group named ‘clamav‘.

fitzcarraldo@ion330ht:~> ls -la /var/lib/clamav
total 343504
drwxr-xr-x 1 vscan vscan        84 Jan 14 20:27 .
drwxr-xr-x 1 root  root        534 Jan 11 12:08 ..
-rw-r--r-- 1 vscan vscan    293670 Jan 11 12:36 bytecode.cvd
-rw-r--r-- 1 vscan vscan 180965376 Jan 14 10:29 daily.cld
-rw-r--r-- 1 vscan vscan        69 Jan 11 12:33 freshclam.dat
-rw-r--r-- 1 vscan vscan 170479789 Jan 11 12:35 main.cvd

Why GeckoLinux (and, I assume, openSUSE) is different from Gentoo Linux and *buntu I don’t know, but I wish Linux distributions were consistent in such cases.

This test command did not work:

fitzcarraldo@ion330ht:~> clamdscan --fdpass --move=/home/fitzcarraldo/virus-quarantine /home/fitzcarraldo/eicarcom2.zip

Anyway, this is what I did (I am not sure precisely which command or commands below were necessary to get things working):

fitzcarraldo@ion330ht:~> setfacl -Rd -m 'u:vscan:rx' /home/fitzcarraldo

(This was the reason I installed the package acl I mentioned earlier.)

Also the scheme described in my aforementioned 2017 post now works in this installation.
 
 
Corrupted filesystem

Not long after I installed GeckoLinux I left the nettop running unattended on several occasions, and a couple of times I returned to find the HDD clicking rapidly (I assume this was the noise of the head continually seeking unsuccessfully), and had to press the machine’s Power switch in order to stop this. As the nettop had been used very little and was in almost new condition, I suspected that the problem was not caused by the HDD but rather by the software installation. I have read about corruption of Btrfs filesystems on several occasions in the past, so I wondered if the problem was caused by Btrfs itself.

I booted the Live pendrive that I had used to install GeckoLinux Rolling LXQt, became the root user (‘sudo su‘) and entered the command ‘btrfs check /dev/sda1‘, which returned no errors. I did some searching on the Web and came across commands such as ‘btrfs check --repair‘ which appeared to be analagous to ‘fsck‘ for other filesystems. It was only later that I found an article ‘How to recover a BTRFS partition‘ with a dire warning about only using that command as a last resort. Before finding that article I ran the following commands:

localhost:/home/linux # btrfs rescue zero-log /dev/sda1
Clearing log on /dev/sda1, previous log_root 0, level 0
localhost:/home/linux # btrfs check --repair /dev/sda1

WARNING:

        Do not use --repair unless you are advised to do so by a developer
        or an experienced user, and then only after having accepted that no
        fsck can successfully repair all types of filesystem corruption. Eg.
        some software or hardware bugs can fatally damage a volume.
        The operation will start in 10 seconds.
        Use Ctrl-C to stop it.

Darn it! I tried the following command to see if it returned an error message:

localhost:/home/linux # btrfs rescue zero-log /dev/sda1
Clearing log on /dev/sda1, previous log_root 0, level 0

Then I found the aforementioned article ‘How to recover a BTRFS partition’ and entered the following command which the article states can be used to rebuild the filesystem metadata tree:

localhost:/home/linux # btrfs rescue chunk-recover /dev/sda1/

It was very slow, occasionally displaying lines ‘Scanning: <n> in dev0‘, so I didn’t hang around to wait for it to complete. When I came back several hours later I found that it had finished and was displaying the final lines of output in the terminal window:

I then ran the ‘rescue zero-log‘ and ‘check‘ commands again to see if there would be an error message:

I hoped the filesystem had indeed been repaired. I then rebooted the machine from the HDD and it has been fine ever since.
 
 
Minor bug in the applications menu entry YaST Filesystem Snapshots

Preferences menu in GeckoLinux LXQt on my 43-inch TV screen

Preferences menu in GeckoLinux LXQt on my 43-inch TV screen.

The entry ‘Preferences’ > ‘YaST Filesystem Snapshots’ in the LXQt Application Menu would not launch Snapper (there was not even an authentication prompt to enter the root user’s password). All the other menu entries under ‘Preferences’ worked as expected. What made this more perplexing was that ‘Filesystem Snapshots’ in the ‘Miscellaneous’ section of the YaST Control Centre (‘Preferences’ > ‘YaST’ in the LXQt application menu) did launch Snapper, and I believe that selection also uses the desktop configuration file /usr/share/applications/YaST2/org.opensuse.yast.Snapper.desktop).

To check if there was something wrong with the desktop configuration file I copied /usr/share/applications/YaST2/org.opensuse.yast.Snapper.desktop to the Desktop, changed its ownership to fitzcarraldo.fitzcarraldo, right-clicked on it and selected ‘Trust this executable’, and it worked as expected when I double-clicked on it. So why did it not work when selected from the application menu?

I then compared the Snapper desktop file to the other YaST2 desktop files in the directory:

ion330ht:/home/fitzcarraldo # grep Exec /usr/share/applications/YaST2/org.opensuse.yast*

/usr/share/applications/YaST2/org.opensuse.yast.Users.desktop:Exec=xdg-su -c "/sbin/yast2 users"

To get the LXQt application menu item ‘Preferences’ > ‘YaST Filesystem Snapshots’ to work I had to do the following:

1. Edit /usr/share/applications/YaST2/org.opensuse.yast.Snapper.desktop and change the following line:

Exec=/usr/bin/xdg-su -c '/sbin/yast2 snapper'

to:

Exec=xdg-su -c "/sbin/yast2 snapper"

2. Run the following command (as root user):

ion330ht:/home/fitzcarraldo # update-desktop-database /usr/share/applications

The file org.opensuse.yast.Alternatives.desktop contains Exec=/usr/bin/xdg-su -c "/sbin/yast2 alternatives" and works, and xdg-su is indeed in the directory /usr/bin/, so I don’t know why the original Snapper desktop file would not work from the LXQt application menu. Anyway, the modified file works, although I could have done without wasting several hours trying to fix the problem, even though it was an inconvenience rather than a show-stopper.
 
 
Applications Menu entries for YaST

I personally found the large number of YaST entries in the Application Menu confusing and unecessary (see the screenshots above and below). It also looks cluttered. The individual YaST entries can also be accessed via ‘Preferences’ > ‘YaST Control Center’, so a shorter menu could have been implemented instead. Also, the three entries ‘Other’ > ‘YaST Software’, ‘Preferences’ > ‘YaST Software’ and ‘Preferences’ > ‘YaST Software Management’ all do the same thing.

ASRock CIR MCE Remote

I should point out that I tinkered with the infrared remote to scratch an itch, because the Rii i8 mini wireless keyboard with touchpad is far superior to a CIR MCE remote and can be used to control the Desktop Environment and any application, including KODI, with ease. MCE remotes are a pain in the neck to configure. The KODI Wiki states: “MCE Remotes – Infrared remote controls made for computers that follow the MCE standard. These remotes should work with Kodi out-of-the-box on Windows and Linux.” Good luck with that!

Anyway, the following are useful background reading on configuring Linux to use infrared remotes:

Here is what I had to do to configure GeckoLinux to recognise the ASRock MCE remote:

1. Ensure the IR receiver is enabled in the ASRock ION 330HT BIOS.

2. Do not install lirc. If it is installed, uninstall it and any associated LIRC packages (except liblirc_client0 which is a dependency of vlc in GeckoLinux/openSUSE, unless you don’t want VLC).

3. The nuvoton-cir module should be loaded automatically at boot if the IR receiver is enabled in the BIOS:

ion330ht:/home/fitzcarraldo # lsmod | grep nuvoton
nuvoton_cir            32768  0
rc_core                65536  6 ir_rc6_decoder,rc_rc6_mce,cec,ir_rc5_decoder,nuvoton_cir
ion330ht:/home/fitzcarraldo # lsmod | grep lirc
ion330ht:/home/fitzcarraldo #

4. Install the package v4l-utils to install the ir-keytable utility, the files /etc/rc_maps.cfg, /lib/udev/rc_keymaps/*.toml and /usr/lib/udev/rules.d/70-infrared.rules

5. Enter the command ‘ir-keytable‘ and you should see some output similar to the following:

ion330ht:/home/fitzcarraldo # ir-keytable
Found /sys/class/rc/rc0/ with:
        Name: Nuvoton w836x7hg Infrared Remote Transceiver

        Repeat delay = 500 ms, repeat period = 125 ms

6. Enter the command ‘ir-keytable -t‘ and press some keys on the remote. You should see something like the following:

# Keymaps table
#
# This table creates an association between a keycode file and a kernel
# driver. It can be used to automatically override a keycode definition.
#
# Although not yet tested, it is mented to be added at udev.
#
# To use, you just need to run:
#       ./ir-keytable -a
#
# Or, if the remote is not the first device:
#       ./ir-keytable -a -s rc1         # for RC at rc1
#

# Format:
#       driver - name of the driver provided via uevent - use * for any driver
#       table -  RC keymap table, provided via uevent - use * for any table
#       file - file name. If directory is not specified, it will default to
#               /etc/rc_keymaps.
# For example:

8. Copy the file /lib/udev/rc_keymaps/rc6_mce.toml to /etc/rc_keymaps/rc6_mce.toml and edit the latter. For example:

9. Run the following command to load the edited keymap and check that it works:

ion330ht:/home/fitzcarraldo # ir-keytable -c -w /etc/rc_keymaps/rc6_mce.toml
Read rc6_mce table
Old keytable cleared
Wrote 60 keycode(s) to driver
Protocols changed to rc-6

By the way, adding ‘-p RC-5,RC-6‘ to that command would select the rc-5 and rc-6 protocols:

ion330ht:/home/fitzcarraldo # ir-keytable -c -p RC-5,RC-6 -w /etc/rc_keymaps/rc6_mce.toml
Read rc6_mce table
Old keytable cleared
Wrote 60 keycode(s) to driver
Protocols changed to rc-5 rc-6

10. Check that the protocols have been enabled and the keymap loaded:

ion330ht:/home/fitzcarraldo # ir-keytable
Found /sys/class/rc/rc0/ with:
        Name: Nuvoton w836x7hg Infrared Remote Transceiver

        Repeat delay = 500 ms, repeat period = 125 ms

11. Reboot.

12. Check that the modified keymap has been loaded:

However, not all the keys on the ASRock remote work in KODI when using the key names in the file rc6_mce.toml listed above. I might have been able to change some of the key names in the file to see if they would have the desired effect in KODI, but it is not worth the hassle when my Rii i8 wireless mini keyboard works perfectly with KODI, all other apps, and the Linux Desktop. I find KODI unintuitive in any case, so there is even less incentive to tinker further with the ASRock CIR MCE remote.

Furthermore, I have now disabled the CIR port in the BIOS because I found that sometimes the nettop was resuming from suspension without me triggering it from either the ASRock CIR MCE remote or the Rii i8 mini keyboard. ‘Boot From Onboard LAN’ is not enabled in the BIOS, so that was not the cause.
 
 
Disabling the nettop’s LEDs

The nettop is on my TV stand and its Power LED, LAN LED and SATA LED could become annoying, especially the blinking power LED when the nettop is in Suspend mode, so I disabled these in the BIOS (‘Good Night LED’ is Enabled to turn them all off).
 
 
Conclusion

After over a decade I am actually using the ASRock ION 330HT nettop and have it connected to my 43-inch TV so that I can browse the Web properly from the comfort of my sofa and play all my FLAC (and MP3, OGG etc.) music files through the sound bar also connected to my TV. The Rii i8 wireless mini keyboard/touchpad works perfectly with the nettop, so the ASRock CIR MCE remote is redundant. Although I have a dedicated DVD player connected to the TV via a Composite Video cable, the nettop is connected via an HDMI cable so the image is nice and sharp.

GeckoLinux Rolling LXQt performs well on the nettop, and looks polished and crisp on the TV screen. I like it a lot so far. Other machines in my home network can browse SMB shares on the nettop, and vice versa, and the nettop can also be accessed using SSH. I need to become familiar with the package manager (GUI and command line) but have not had any trouble so far. The Btrfs filesystem ‘hiccup’ I mentioned earlier worries me a little, but I have had no further trouble since I repaired the filesystem. And I have actually used Snapper a couple of times to recover files I deleted too hastily. So GeckoLinux gets a thumbs up from me.
