SUMMARY When having a multi-monitor setup and let the screens automatically lock and switch themselves off - as set up in Screen Locking settings - the non-primary display will always freeze or will simply not turn on again. STEPS TO REPRODUCE 1. Set up automatic Screen Locking in KDE settings 2. Wait for the displays to turn off 3. Wake the system OBSERVED RESULT One screen (secondary in this case) freezes or is unable to turn on again. EXPECTED RESULT All screens should work the same as before screen locking SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 6.0.5 KDE Frameworks Version: 6.2.0 Qt Version: 6.7.1 ADDITIONAL INFORMATION Graphics Platform: Wayland GPU: Nvidia RTX 4070 Ti Graphics driver: Nvidia proprietary 550.78
NVIDIA driver issue, maybe?
Update: as it turns out, it has something to do with KDEs energy saving screen dim/turn off setting, not the screen lock itself. (In reply to bugreport.outscore586 from comment #0)
Please attach the output of drm_info, once for when the output is working correctly, and once when it doesn't turn on again. The output of > journalctl --user-unit plasma-kwin_wayland --boot 0 after triggering the problem would also be useful
