This has apparently been a problem for a few months now, and can effect Intel and Nvidia graphics too, but AMD is the most susceptible, and Gnome on Wayland seems to trigger the issue the most. A developer of Kwin explains in a comment on the bug report what’s causing it.
My “Favorite”: Pageflip Timeouts
Judging by how often I come across this issue in bug triage, if you’re reading this, chances aren’t too terrible that you’ve heard of this one already, possibly even seen it yourself in the form of
kwin_wayland_drm: Pageflip timed out! This is a bug in the amdgpu kernel driver kwin_wayland_drm: Please report this at https://gitlab.freedesktop.org/drm/amd/-/is>sues kwin_wayland_drm: With the output of 'sudo dmesg' and 'journalctl --user-unit plasma->kwin_wayland > --boot 0'in your own system logs at some point. To be clear, this is just an example and it does not only affect amdgpu. I’ve seen the same with NVidia and Intel too, but as amdgpu’s GPU resets have been a lot less reliable in >the past, it’s been a bigger issue for them.
Basically, pageflip timeouts are when the compositor does an atomic commit through KMS, and then waits for that to complete… forever. When this happens, the kernel literally doesn’t allow the compositor to present to the screen anymore, so the screen is completely frozen forever, which is >very bad, to state the obvious.
Fixing all the individual causes of the problem hasn’t really worked out so well, and this is a bad enough situation that there should be a way out when it does happen. We discussed how to do this, and I’m happy >to report that we figured out a way forward:
- we need a new callback in KMS that tells compositors when a pageflip failed and will never arrive
- drivers need to support resetting the display-driver bits of the GPU to recover it
- if the driver entirely fails to recover in the absolute worst case, it should send a device wedged event, which tells the compositor it should try to reload the entire driver / device
I have this issue and it was plagueing me for 2 days straight and freezing/restarting my machine. Has gone away for a few days now on its own 🤷♂️
If anyone happens to see this, the issue came back and has been rather annoying. What fixed it for me was adding some kernel parameters that I read have to do with the bug. I am on bazzite btw
rpm-ostree kargs --append-if-missing=amdgpu.aspm=0 amdgpu.runpm=0 amdgpu.bapm=0
This isn’t a new thing. I believe the issue stems from a specific fix for a security flag that got implemented in 2021, but I can’t find it now.
Basically they’re implementing a flag to stop an overrun attack. This is still a thing that happens on Windows BTW, but the Radeon userspace software is supposed to intervene. There is no counterpart for any other platforms.
I used to have an issue with my screen either freezing or going blank and staying this way until after initiating a soft reboot. Disabling Panel Self Refresh (PSR) on my daily driver is what fixed that for me, but this workaround only applies to laptops/tablets and seems to not be the exact same issue reported here.
I thought maybe this is the issue I have been having but this seems different. I think mine is a memory usage issue with Firefox, potentially with using YouTube through Firefox specifically
I might have been experiencing this issue for the longest time. System fully locks up and is completely unresponsive. Happened on every distro I used.
Last distro I had it on was Artix Linux. Then I tried Alpine and I don’t think I’ve had it happen since.
Oh THAT’s what the random freezes were. Got them sporadically on my Arch machine for a couple of years, and never figured out exactly why. (Now I’m using a different laptop that still has AMD graphics, but I haven’t got a freeze yet.)
I’ve been able to avoid it from happening as long as the DE is using X11, seemingly.
I don’t know if I’m having this exact issue but what stopped my AMD APU laptop with 2 external displays from freezing all the time is setting my main external display to 120Hz instead of the maximum 170. Pretty much never had a freeze after that.
I had amdgpu complete freezes for the longest time. Logs said it was ‘lost from bus’. Turned out it only happened while running Libre Office. Never found a fix/workaround, so I basically don’t do work in Linux on my amd machine.
