Wayland multi-monitor screen freeze

Right now wayland multi-monitor is working mostly except this one intermittent issue. Sometimes one of my 3 monitors freezes. I can still right click the app icon on another monitor and move an app off the frozen screen to a non-frozen screen, but I can’t do anything with that monitor. I noticed this happens sometimes when I am playing games. That could be unrelated because that is what I do most the time on the computer now. I did notice though once Firefox crashes sometimes the screen will come back unfrozen. So not really sure where the issue comes from.

Sorry to be the bearer of bad news, but that’s one of about a million known bugs in the driver. We’re a year or two away from working nvidia drivers yet.

The workaround is to switch to a TTY (ctrl+alt+F*) and back.

You may check if you get a

kwin_wayland_drm: Pageflip timed out! This is a kernel bug

message at the syslog like i still occasionally do with such freezes (not even actively using my 4070 when that happens, so I can not really blame that driver).

Just tried that supposedly workaround and I can NOT recommend it as it caused everything to lockup and I had to force shutdown my Computer. Not recommended at all

What always worked for me was logout and back in.

My apologies, I read that trick elsewhere and it has worked for several people including myself and yours is the first problem I heard of it. It’s a bit quicker and easier than log out/in but next time, I’ll recommend people try it safely to be sure they don’t have this problem.
