What happened:
- I launched a game via proton(GTAV, lutris, epic games) and suddenly the screen turned black/switched to standby. My PC didn't react to anything; I had to shut it down by cutting off power.
- If I login with SDDM the same thing happens after the splash screen animation.
- I can switch to the tty but it needs almost a minute to "load" it.
- I have another DE/WM installed, it works flawlessly(same user)
- If I login to plasma with another user it also works as expected
- Removing the .config file in the users directory didn't change anything
- Idk if it is even related but trying to launch plasma_session from a terminal returns
org.kde.plasma.session: process job "kcminit_startup" finished with exit code 0
- Launching
plasmashell
from terminal in a WM spits out a few warnings but works just fine(plasma panels etc. appear) - I couldn't find anything in /var/log and with journalctl
- KDE Plasma, Xorg, Arch Linux, Zen kernel
What can I do?
Has someone an idea what causes the trouble or how I can find useful (debugging)information/logs?
Thanks in advance :)
