I’ve been using Rawhide for a while but decided to go back to a stable version of Fedora. I burned a Fedora 34 KDE live disc, verified the image, and then used my existing BTRFS volume for installation. I created a new subvolume for the new root filesystem and used my old volumes at their old mount points. Installation went smoothly and after booting into F34 I deleted the old root subvolume and its snapshots.
I have a problem with the new installation though where the lock screen is broken after suspending. If I allow the computer to sleep, then wake it, I get a message saying that the lock screen is broken and I need to log into another terminal and run loginctl unlock-session 2. If I do that and then switch back to my main session, the screen is covered in graphical artifacts to the point that it’s unusable. “Beneath” these artifacts, everything works like it should. I took a screenshot with the Print Screen key and it looked normal, and I can move to the bottom left of the screen and see the artifacts change colors where the menu should be when I click.
The only thing that seems to fix this is to go back to the other terminal and run startx, which attempts to start an X session and immediately disconnects. After that, I can go back to the first terminal and my graphical session is there with no artifacts. Another thing to note, this doesn’t work if I don’t switch back to the original terminal after the loginctl command. The process has to be CTRL+ALT+F4 → loginctl unlock-session 2 → CTRL+ALT+F1 → CTRL+ALT+F4 → startx → CTRL+ALT+F1.
I’ve tried reinstalling all packages and running rpmconf -a to ensure there are no old config files left over from Rawhide that could be messing something up. What else could be breaking the lock screen?
