Description SavciSV 2025-09-25 12:57:29 UTC 
SUMMARY
Clicking switch user on lock screen completely freezes the entire OS, can't even access TTY or shutdown from the button, I have to hard reset. (And yes, I tried waiting for more than 15min before.)

STEPS TO REPRODUCE
1. On a plasma session, press Meta+L to go to lockscreen.
2. Press the "Switch user button from there.

OBSERVED RESULT
The entire system freezes, making you even unable to access another TTY or shutdown using the power button.

EXPECTED RESULT
Normally bringing you to the login screen where you can choose another user.

Can't reproduce on KDE Linux, and I don't recall being able to reproduce this on Fedora KDE 42.

Can you get a journal log from around the time it happened?

If you have to force-shutdown using the power button, you can get the log from the prior boot with `journalctl -b -1 | head -n 100`
