I can use plasma normally after login but if Plasma locks my session after the set time (doesn’t seem to matter if it’s just 5mins or 30mins), when I unlock it, I either get a black task manager or a black screen. Every program is still open, and I can use Alt+Tab to switch between them. I can also hit the Meta key, and the application dashboard shows up. To restore everything, I have to restart Plasma with:
kquitapp5 plasmashell || killall plasmashell && kstart5 plasmashell &
However, if I lock the session manually, the issue doesn’t happen.
Output of plasmashell --version && kf5-config --version (left the QThreadStorage output there—it didn’t appear before, but I’m getting it under 6.3):
plasmashell 6.3.0
QThreadStorage: Thread 0x55b27ebbd1f0 exited after QThreadStorage 8 destroyed
QThreadStorage: Thread 0x55b27ebbd1f0 exited after QThreadStorage 3 destroyed
QThreadStorage: Thread 0x55b27ebbd1f0 exited after QThreadStorage 2 destroyed
Qt: 5.15.15
KDE Frameworks: 5.116.0
kf5-config: 1.0
My GPU is an integrated Intel for i7-1165G7.
Some logs from journalctl from right before the screen locked and after I ran the command to restart plasma from konsole:
