[email protected] changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |matter_alienable031@inceleb | |ratus.com --- Comment #4 from [email protected] --- I'm experiencing an issue related to session locking. Initially, I thought it was due to session locking itself, but I later realized that the issue only occurs when the screen is set to turn off. When I disabled screen power-off, the issue no longer appeared. Additionally, I see an "kwin_wayland[26256]: unknown active output" message in the logs. I’m not using the Night Light feature, and the system crashes intermittently. Instead of freezing on the lock screen, kwin crashes and automatically restarts. However, after unlocking the screen, the entire display session is wiped, and I get an error when attempting to open the Power Management window. STEPS TO REPRODUCE 1. Lock the session. 2. Allow the system to turn off the screen. 3. Try to unlock the session after the screen turns off. EXPECTED BEHAVIOR: * The screen should unlock without any crashes or session wipes. * The Power Management window should open without errors. ACTUAL BEHAVIOR: * The display session is wiped after unlocking the screen (all applications are closed, no tray non-default tray icons are visible, etc). * I get an error when trying to access the Power Management window. * kwin crashes with "kwin_wayland[26256]: unknown active output" log message ADDITIONAL INFORMATION: * Night Light is not enabled. * The issue seems resolved by disabling screen power-off. * The system is up to date.
