org.gnome.SettingsDaemon.XSettings.service fails to restart properly after AMD GPU reset event

[Jozef Behran]

GNOME did not recover successfully from a GPU reset event. The system is still running but no direct interaction with it is possible. Keyboard appears to be running but the screen shows what was on it when the GPU crashed.

Attached is a SYSLOG fragment showing the problem. At 04:12:09 the GPU crashed. At 04:17:06 the crash was detected and a GPU reset was issued. At 04:17:07 the org.gnome.SettingsDaemon.XSettings.service crashed with "failure status". Subsequent attempts to restart it (10 shown) caused it to terminate with "timeout status".

I reported this originally as an xorg bug because the computer became completely unusable and the only way to recover was a hard power-off. I could not even switch to another virtual console.

I can't tell which package exactly this occured in because the package search does not work properly. It might be xorg itself but the failing org.gnome.SettingsDaemon.XSettings.service suggests the problem to be somewhere else.

It looks the syslog fragment I was talking about in the bug report got lost in the bug submission process. Here it is.

[Jozef Behran (jctech)]

Ok, now I realized that my system runs on Wayland. So no xorg problem.

[Jozef Behran (jctech)]

Probably xwayland as my setup does not involve running xorg. Or gnome: why is
org.gnome.SettingsDaemon.XSettings.service needed on Wayland? Gnome does not use xwayland to run itself, it runs on wayland natively.

[Jozef Behran (jctech)]

When I think about it now, I started to suspect that the Wayland compositor in Gnome went wacko when the GPU reset occured. Unfortunately, I can't replicate this as I have no idea how to easily trigger a GPU reset. Generally submitting a GPU load that overloads it should do the trick but constructing such a load is currently beyond my abilities.
