Hey guys, Ive been running PoP OS for more than a year without any big issues until today. I did a reboot (with checkmark to do updates) and after that PC got stuck at MBO logo. After reading a bit I rebooted again and was holding space button -> chose old kernel and PC started. One screen was just black while the other one was using super low resolution. I went to pop_shop and downgraded video drivers from 555 to 470 and eddited /boot/efi/loader/loader.conf to default Pop_OS-oldkern rebooted and viola its booting fine. Then I noticed my app PrusaSlicer (flatpak) doesnt show the Platter (main tab) and it crashes if I try to slice. I read it could be graphic driver related. Then I was struggling to update drivers to 555 again and eventually succeeded using sudo apt remove ~nnvidia and sudo apt install pop-desktop system76-driver-nvidia. I believe Im using old kernel and new gpu drivers, but still have an issue with PrusaSlicer. Anyone know a solution?

When I had only one screen working (at low resolution) PrusaSlicer was working fine…reinstall doesnt help at all

Thx in advance

    When you change your nvidia driver version, you also need to do a “flatpak update” so that you have the matching nvidia library version.

      Hehe. I have been switching from nvidia to amd and back to nvidia. I guess next switch should be amd again

    Idk, but this last nvidia update broke things for me. Changing my display with ARandR wouldn’t work, I’d get a black screen with a mouse cursor and it would never recover, and the display driver would crash when waking the computer from sleep. I ended up reverting to the 470 drivers and that fixed it for me.

      When you say last nvidia update, when was that? I had some updates few days ago and everything went smooth, but today things went south. Is there any way I can confirm Im having gpu driver issue or kernel issue or both?

        I don’t knowwww. I just for back from an out of town trip that lasted a week and a half and I remember updating everything when I got back.

        So I’m really just assuming it was a graphics driver update, especially since rolling back my drivers fixed the issue.
