Fix Crostini Wayland/X (sommelier) service

Raw

20180819-crostini_sommelier_fix.md

If you can't get X11 or Wayland GUI Linux apps to start anymore on Chrome OS, try the following.

In the Terminal app, this will show the status of your systemd user services/units:

systemctl --user

If [email protected] and [email protected] show a failed status, the following worked for me:

sudo ln -s /opt/google/cros-containers/bin/sommelier.elf /usr/bin/
systemctl --user restart [email protected]
systemctl --user restart [email protected]
export DISPLAY=:0

Check again to see if those services are started now:

systemctl --user

Hopefully now X/Wayland apps work again.

The Chrome launcher does not start these apps, however (it used to work before). So I need to launch them from the terminal.

just got the dev update on my pixelbook i5, sadly fix isn't working for me. only [email protected] is failing:

$ systemctl --user
● [email protected]               loaded failed     failed    X11 sommelier at display 0                    

$ sudo ln -s /opt/google/cros-containers/bin/sommelier.elf /usr/bin/
ln: failed to create symbolic link '/usr/bin/sommelier.elf': File exists

$ systemctl --user restart [email protected]
Job for [email protected] failed because the control process exited with error code.
See "systemctl status [email protected]" and "journalctl -xe" for details.

$ systemctl status [email protected]
Unit [email protected] could not be found.

tried running export DISPLAY=:0 before systemctl --user restart [email protected], no change.

Any ideas would be greatly appreciated.

update:
reboot, launch terminal app, systemctl --user shows [email protected] running;
starting the launcher while terminal is running crashes the GUI (which then reloads automagically);
rerunning systemctl --user in still open terminal app shows [email protected] failed, and none of the above steps seem to revive it.

@jpelton-stroud - I also did see this, and some reboots fixed it.

I think chrome launcher for x11/wayland apps is currently broken, and trying to use it actually leads to this error on the container. Not using it, but just the terminal, to start x11/wayland apps does work.

It seems that both services are running on my Lenovo Pyro, but I will make a further check.

[email protected] loaded active running X11 sommelier at display 0
[email protected] loaded active running Master sommelier listening on socket wayland-0

Thanks for the hint.
