Created attachment 167293 [details] backtrace for all threads SUMMARY Hi there, since upgrading to KDE / Plasma 6 kscreenlocker_greet sporadically locks up right after activating the lock screen: The mouse pointer disappears, the clock does not advance and the process can only be killed with SIGKILL. I am using a ThinkPad P1 Gen 5 (w/ Intel GPU) with an external display attached via a Dock and DisplayPort. The session is based on Wayland. I hope the attached backtrace is somewhat useful. If not, please let me know and I'll try to get a better one. STEPS TO REPRODUCE 1. Lock the screen 2. Play the deadlock lottery 3. If you're lucky, the lockscreen freezes OBSERVED RESULT The lock screen freezes. The session can not be unlocked. EXPECTED RESULT The lock screen does not freeze. The session can be unlocked. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 6.0.2 KDE Frameworks Version: 6.0.2 Qt Version: 6.6.2 ADDITIONAL INFORMATION
Created attachment 167471 [details] backtrace for all threads with complete debug symbols The lockup just happened again and I have been able to capture a backtrace with complete debug symbols courtesy of debuginfod.
This seems to happen if you move the mouse to cancel the lock when it was not fully locked.
I experience this on X11 though.
