Monitor freezes every couple of hours

Graphics / Linux Linux
1

Hello,
once every couple of hours, my system freezes completely.
To “unstuck” it, I have to switch TTY (CTRL+ALT+F3), then go back to the graphical session (CTRL+ALT+F2). Then, the computer works, but has a lower framerate (probably 60hz); I have to switch the framerate to a lower value, then bump it up again.

When this happens, I see this in dmesg:

[18096.465785] [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000a00] Flip event timeout on head 0
[18099.665638] [drm:nv_drm_atomic_commit [nvidia_drm]] *ERROR* [nvidia-drm] [GPU ID 0x00000a00] Flip event timeout on head 0

Some specs:
I have a 3090 graphics card, and a 4k, 240hz, HDR monitor. I use Gnome, with HDR turned on, but the issue occurred even with HDR off, and using a lower framerate.

Same thing happening to me with 3070 and 5800x3D on Arch Linux.

Have you tried setting kwinrc to:

[Wayland]
DirectScanout=false

If you’re running Wayland? I’m testing it out and haven’t had a hang since, but I also haven’t been using my PC much. Worth a shot.

This bug has been present for months now and they still haven’t come out with a fix.

I use Gnome, so no kwinrc

I never had an issue since driver version 575. Feel free to consider this resolved.
