I have hybrid graphics configuration managed by nvidia-prime outputting the image on external monitor through hdmi cable.
Everything went well till I rebooted from the last update which contained nvidia 525.60.11.
The issue is that system displayed on external monitor hangs out significantly on every basic action: activating any opened window takes up to 1 min, as well as switching between icons or window buttons or launching any app, video renders extremely slow; making work practically impossible. While on the main display (laptop) everything goes fluently.
I tried switching to previous kernel (5.15), reinstalling nvidia-prime, linux**-nvidia, nvidia-utils (also mhwd -a pci nonfree 0300), removing .Xauthority and nvidia.conf files, but nothing helped.
Done. Now the external monitor only displays an “empty” wallpaper and checking-in/applying it as "Primary" (in Display configuration) does not make any effect. (so when I run some youtube HD video: the video runs on laptop but the sound goes from the external display)
Anything else should be made?
unfortunately that was it, there were some recent issues with dual monitor setup on kde and nvidia, and this helped in some cases…
try creating a new test user, reboot, log in with it and see if it helped
I’ve tried to login in with my test user and had the same issue.
Another observation is that when dragging some window out of the right boundary of the active screen and making it appear on external monitor - it seems rendering fine there. It looks like it troubles with dual monitor arrangement.
But, as I mentioned earlier, checking-in/applying it (ext. monitor) as "Primary" (in Display configuration) does not make any effect, more precisely, that action only pulls up the taskbar there but all new apps and windows still open on laptop display.
try reinstalling the drivers: sudo mhwd -r pci video-hybrid-intel-nvidia-prime
install them again: sudo mhwd -i pci video-hybrid-intel-nvidia-prime
disconnect the external monitor;
delete again the kscreen folder;
reboot - the monitor still disconnected - then connect it again when you are in desktop
When I check Replica of: builtin screen for external monitor - it “copies” the output, but that’s not what’s needed.
When I use Fn + F8 shortcut I’m able to dim the builtin screen and get the output on external, but it slows down the system extremely.
should I proceed with sudo mhwd -i pci video-hybrid-intel-nvidia-470xx-prime ?
how to recover back normal taskbar icons and window fonts ?
I’ve installed video-hybrid-intel-nvidia-470xx-prime, rebooted and see no changes.
The icons and fonts has recovered.
I noticed that even just checking off Enabled on “Buil-in Screen” causes system to hang out/slow down.
Should I proceed with sudo DOWNGRADE_FROM_ALA=1 downgrade kscreen libkscreen ?
yes, you have nothing to lose… but you have to install the package downgrade first, then proceed with the command, and select the previous versions, where it worked, reboot … (thats assuming kscreen is the cause)
well thats unfortunate… did you downgrade both of the packages, the kscreen + libkscreen?
do you have a timeshift backup?
also provide logs, maybe there will be something: journalctl -b0 -p4 --no-pager
