Xorg crashes after waking from suspend and connected to ext. screen

I have this issue where the Xorg server crashes / core dumps (not always but sometimes) when the laptop wakes from suspend while connected to my dock station and external screen.
This seems to be related to the AMD GPU driver but not sure if it's a misconfiguration on my end or a bug that should be reported.

I've dug around for a while and I've seen some slightly similar issues but nothing recent that I could find.
Any ideas on where to start?

Re: Xorg crashes after waking from suspend and connected to ext. screen

related to the AMD GPU driver

Do you get the same behavior (but maybe a better backtrace) w/ the modesetting driver (ie. when removing xf86-video-amdgpu and all config files referencing it)?

Re: Xorg crashes after waking from suspend and connected to ext. screen

I haven't tried but the thing is reproducing the issue is tricky as it's not consistent.
It has sth to do with the laptop being suspended for a while and being connected to the docking station, then getting removed while still in suspend and then trying to wake it up.
It doesn't always crash but I would say probably around 1 in 10 times.

Would I be able to use Xorg with no performance difference if I uninstall the driver, given that the laptop only has an integrated GPU?

Re: Xorg crashes after waking from suspend and connected to ext. screen

*No* *difference* is pretty specific, but it should not vary a lot (up or down, depending on the context)

Are you running a plasma session?
The kscreen daemon might trigger this.

Re: Xorg crashes after waking from suspend and connected to ext. screen

Ah I see.
I'm running only i3 with sddm.
If it turns out it's the driver that causes this, what would be the approach to fixing this?

Re: Xorg crashes after waking from suspend and connected to ext. screen

Ifff it is xf86-video-amdgpu: not using it.
The trend is towards the modesetting driver on top of the kernel module anyway (b/c wayland doesn't rely on those drivers at all)

Re: Xorg crashes after waking from suspend and connected to ext. screen

I'll try to reproduce and update.
And excuse my ignorance, but would stuff like hardware video acceleration still work without the xf86-video-amdgpu driver? or are they not related?
From the dependency of the packages, it seems that xf86-video-amdgpu depends on mesa, for example, so I'm guessing it would still work?

They are not related, it will still work.

Re: Xorg crashes after waking from suspend and connected to ext. screen

After uninstalling xf86-video-amdgpu the crashes are gone however they are replaced by a black screen that freezes the system when I try to disconnect the laptop from the dock (TB4 if it matters)
The lines in the journalctl logs that seems interesting:

Is this related to uninstalling the amdgpu driver? Is it fixable?

Re: Xorg crashes after waking from suspend and connected to ext. screen

That's the thunderbolt bridge

freezes the system

You seem to be able to login from TTY2 fine?

What's the output of

xrandr --display :0

in that situation?

Do you somehow rely on the output being moved from some external display to the internal display when disconnecting from the dock or is the internal output always active?

Re: Xorg crashes after waking from suspend and connected to ext. screen

Yes I was able to (after a bit of banging on all keys and disconnecting the dock) to switch to TTY2 and get the logs once. And yes it seems that when I returned back to TTY1 that the system was still trying to output on the external screen even though it was disconnected.  When I opened arandr, the external screen was still active. And my windows that were on the external display was not moved to the internal one.

Re: Xorg crashes after waking from suspend and connected to ext. screen

https://aur.archlinux.org/packages/x-on-resize - but the actual xrandr ouptut would probably be helpful.
(arandr is an abstracting wrapper)

I guess deactivating the external output before S3/detach from dock/wake would prevent the problems?

Re: Xorg crashes after waking from suspend and connected to ext. screen

Sorry it has been a while but the system has been behaving until today when it froze upon waking from suspend while connected to the TB4 dock. This time I couldn't even switch to TTY.
The main issue seems to be the following:

which eventually leads to

I have found the following issue: https://gitlab.freedesktop.org/drm/amd/-/issues/2068 which seems to be similar to mine.
Is there a way that I can fix the crashes until a root cause is found?

I can try that, do you have suggestions for hooks to plug deactivation of the external display into? I mean a hook for pre-S3 and pre detach from dock?

Re: Xorg crashes after waking from suspend and connected to ext. screen

Haha smile That would be nice big_smile

I've been trying the following:
Using linux-zen kernel
Replace HDMI with DP (as I've read in the forums that it can be a bit unreliable)

So far I haven't been having issues but will update again in a couple of days to confirm, as the crashes are triggered by long suspends.

Re: Xorg crashes after waking from suspend and connected to ext. screen

After using linux-zen and DP instead of HDMI, the frequency of the issue has drastically decreased. I don't have the GPU timeout and reset regularly after suspend.
However it still happens, seems to be related to GPU usage and (according to drm/amd issue) the voltage changes.
At this point, I'm not sure if there's sth that I can do, since it seems to be a long ongoing issue with on amd's backlog.
But just thought I share my latest learnings and latest journal ctl log with the GPU timeout, reset and freeze.

Yup you called it amdgpu.dpm=0 breaks the boot.
I've left the other parameters just in case.
Also another update is that TLP somehow makes things worse. Crashes are way more frequent.
