I think I might have found an answer. After googling and reading and rinsing and repeating I learned that the device scan at boot should be done by the initramfs. So I extracted the contents of my initramfs with: cp /boot/initramfs-debian* /tmp/initramfs.xz cd /tmp unxz *.xz cpio -i -d < initramfs The first place I looked was in the "init" script in the root on the cpio and I found this code section starting at line 383: # Setup btrfs, see bug 303529 setup_btrfsctl # start BTRFS volume detection [ -x /sbin/btrfsctl ] && /sbin/btrfsctl -a The command "btrfsctl" is deprecated. It has been replaced with "btrfs". Inside the cpio's /sbin "brtfs" exists but "btrfsctl" does not: /tmp $ ls ./sbin blkid btrfs init mdadm mdmon modprobe If I am understanding what I have read then I think the section of the init script should read: # Setup btrfs setup_btrfs # start BTRFS volume detection [ -x /sbin/btrfs ] && /sbin/btrfs device scan

For several weeks I have had this issue on my server and I would like to resolve it before I upgrade the hardware this week. Basically, btrfs partitions are not recognized when the system boots up. In order to reboot the server I have to stop everything on my network that relies on NFS or LXD containers from the server. Then attach a keyboard, mouse and monitor to the server and boot it up, stop the NFS daemon, run btrfs device scan, then run mount -a, then start NFS and LXD and then start my containers. Then I disconnect my keyboard, mouse, and monitor and reconnect them to my desktop and boot it, then while it is coming up I make sure my tablet and phone don't need rebooting to reconnect to my server. After that I can start using my computers again. So where should I be looking to find out why my server isn't scanning for btrfs devices on boot? I have looked in dmesg and syslog, but the only info there comes from when the system tries to mount the filesystems and logs the fact that they are missing. Manually calling btrfs device scan as root will find the drives and then they can be mounted without issue. Therefor I think that the automated device scan is no longer functioning. What component should be issuing this? What other logs or configuration files should I be looking at?

I think portage wants you to set the introspection USEFLAG for x11-libs/pango in /etc/portage/package.use, and then (most likely) you will have to add it for number of other gtk related packages as well. I have run into something similar with both LXDE and virt-manager. TBH, I don't really know what the introspection USEFLAG does or why it wants it. I hope that helps.

Getting closer! I have sound from Steam if after every reboot on my desktop system I start the steam-nvidia-launcher then open another terminal and do: pusleaudio --kill pulseaudio --start After doing this I can even start games the require Steam Play, A.K.A. Proton, A.K.A. Steam's fork of WINE (and why fsck -sake don't they just call it WINE?! I mean it's not like it's a secret or anything!) However I cannot launch games the require Vulkan. So no X4: Foundations or No Man's Sky. At this point I am not only getting frustrated, I am getting drunk. After all, why pound my head against this when I could be pounding it against my toilet?

I have this issue on my server at the moment, but I am not using KDE on it. It is still running Funtoo 1.3 and I discovered this while trying to rebuild the system with -mtune generic so I could upgrade the hardware next month without a reinstall. This issue stopped my "emerge -e @world" in it's tracks. On my desktop I just did a fresh install of Funtoo 1.4 and was able to install sys-apps/accountsservice without issues. I haven't looked into the issue any further because I am fighting with I desktop. If I win I get to use Steam in Funtoo. If it wins I have to keep Ubuntu installed on one of my disk partitions.

At some point in the future it would be nice to add automatic updates to the container so that it doesn't become a security risk if the user ignores it for too long: https://help.ubuntu.com/lts/serverguide/automatic-updates.html But lets get other things working before we try for bells and whistles.

For testing purposes I did a container wipe before I started this post. Both the host and the container return :0 when told to "echo $DISPLAY". The when told "xhost +local:" the host returned " bash: xhost: command not found" so I did "emerge -va xhost" then issued "xhost +local:" again and (because the containter was still running) the Steam Client launched immediately. I was also able to launch glxgears as root as well as with the steam account. Inside the container both the root account and the steam account can generate white noise with "pacat -vvvv /dev/urandom". However Steam itself still refuses to use pusleaudio. No sound was played by the Steam client or by Euro Truck Simulator 2 when it was installed. I am attaching a copy of the full error log (from /home/steam/.steam/error.log inside the container) in the hope you can find a clue in it that I cannot. error.log

Had another thought. How hard would it be to script the creation of a empty ext4 filesystem image that gets mounted into the Steam image? This could be used to store backups of the game installation files and be persistent across Steam container wipes.

A bit more info about things that do not work as expected: Trying to launch any game the using Steam Play, A.K.A. Proton, A.K.A. Steam's fork of WINE will cause a segfault in vgui2_s.so Steam seems to trying to use ALSA as it's audio backend. Here is a bit of /home/steam/.steam/error.log: AL lib: (WW) alc_initconfig: Failed to initialize backend "pulse" ALSA lib confmisc.c:767:(parse_card) cannot find card '0' ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory ALSA lib confmisc.c:1246:(snd_func_refer) error evaluating name ALSA lib conf.c:4528:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:5007:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM default AL lib: (EE) ALCplaybackAlsa_open: Could not open playback device 'default': No such file or directory That is added to the log every time I launch Euro Truck Simulator 2.

OK, I made a huge step forward. The display couldn't be opened and I was reminded of errors I had seen while learning how to use x11vnc. That problem was caused because x11vnc couldn't find a valid .Xauthority file. So while trying to find a way to pass the tell glxgears to use a valid .Xauthority file I found this question and answer on askubuntu.com: https://askubuntu.com/questions/827070/cant-run-glxgears-in-root-on-lxc-2-0-container I passed my user account xauth into the steam container's root account I was able to run glxgears as root. On host do: $ xauth list your-host-name/unix:0 MIT-MAGIC-COOKIE-1 <Image a long hexadecimal string here> After starting the container and attaching to it: # xauth add $DISPLAY . <The long hexadecimal string from you host goes here> Now glxgears runs as root. But steam still couldn't open a display. So inside the container: # su steam $ xauth add $DISPLAY . <The long hexadecimal string from your host goes here> At this point Steam should begin to install. I have a lot...a whole lot of windows spamming my desktop telling that these libraries are missing and that Steam might fail to run: Error: You are missing the following 32-bit libraries, and Steam may not run: libXtst.so.6 libpulse.so.0 libva.so.1 libbz2.so.1.0 libvdpau.so.1 libva.so.1 libva-x11.so.1 But Steam did run and I was able to login, install Euro Truck Simulator 2 and play it. Without sound. No sound in game and no sound in the Steam client. Even the movies in the Steam store were silent. But it did run and the frame rates was exactly what I expected them to be. The systemd-logind spam also stopped apearring in dmesg at this point. Just to be sure I double check that pulseaudio was giving me output in the container using "pacat -vvvv /dev/urandom" and it worked for both root and steam users. So that is where I am at now. I need food and rest so I will be back later.

This is from inside the docker container, looking at the display hardware: root@2b739c474a3e:/# ls -al /dev/nvi* crw-rw-rw- 1 root root 195, 254 Oct 29 01:34 /dev/nvidia-modeset crw-rw-rw- 1 root root 240, 0 Oct 29 01:34 /dev/nvidia-uvm crw-rw-rw- 1 root root 240, 1 Oct 29 01:34 /dev/nvidia-uvm-tools crw-rw-rw- 1 root root 195, 0 Oct 29 01:34 /dev/nvidia0 crw-rw-rw- 1 root root 195, 255 Oct 29 01:34 /dev/nvidiactl root@2b739c474a3e:/# ls /dev/dri card0 renderD128 root@2b739c474a3e:/# lspci | grep VGA 08:00.0 VGA compatible controller: NVIDIA Corporation Device 1f02 (rev a1)

This is from dmesg on the host. The block of messages below repeats as long as the steam-nvidia-launcher is active: [53909.798612] systemd-logind[23]: Failed to start user slice user-1000.slice, ignoring: Launch helper exited with unknown return code 1 (org.freedesktop.DBus.Error.Spawn.ChildExited) [53909.801133] systemd-logind[23]: Failed to start user service, ignoring: Launch helper exited with unknown return code 1 [53909.803728] systemd-logind[23]: Failed to start session scope session-1.scope: Launch helper exited with unknown return code 1 [53911.689537] systemd-logind[23]: Failed to start user service, ignoring: Launch helper exited with unknown return code 1 [53911.692124] systemd-logind[23]: Failed to start session scope session-1.scope: Launch helper exited with unknown return code 1 [53911.695034] systemd-logind[23]: Failed to stop user service: Launch helper exited with unknown return code 1 [53911.697568] systemd-logind[23]: Failed to stop user slice: Launch helper exited with unknown return code 1 [53911.719384] systemd-logind[23]: Attempted to remove disk file system, and we can't allow that.

I tried it last night. It cannot open the display: oot@2b739c474a3e:/# glxgears No protocol specified Error: couldn't open display :0 Is there anything else I should be trying?
