Sup guys I'm having this problem screen and I'm pretty clueless and do not know where to start debugging it

I'm running KDE under wayland

GPU: NVIDIA GeForce RTX 4070 Max-Q / Mobile [Discrete]
Kernel: Linux 6.18.6-arch1-1

I'm currently using the proprietary nvidia driver, with GSP disabled, but even when I was using the nvidia-open package this was already happening, its not always that this happen, when it happens I need to reboot once or twice.

Does restarting SDDM/KDE suffice?

Hey Seth, updating here. No it did not help at all

Please post the journal of an affected boot, eg.

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

for the previous ("-1") one.

Edit: do NOT reboot out of this w/ the power button, frenetically press ctrl+alt+del or in doubt use the https://wiki.archlinux.org/title/Keyboa … el_(SysRq) + REISUB

Sup again Seth, I can actually normally login on the affected boot, the monitor just get shrink, would not be easier to just get the jourrnalctl of this boot?

If you can operate the system under those conditions, sure.
Or does the output "fix" with the login?
