These logs seem relevant Dec 07 10:49:19 fw kwin_wayland[1600]: kwin_wayland_drm: Atomic modeset test failed! Invalid argument Dec 07 10:49:19 fw kwin_wayland[1600]: kwin_wayland_drm: Setting dpms mode failed! Can I ask you to follow the instructions here to get us some detailed logs? This will help us investigate what's causing the failed modesets. https://invent.kde.org/plasma/kwin/-/wikis/Debugging/Debugging-DRM-issues Thanks! Created attachment 188834 [details]

Created attachment 187408 [details] journalctl log SUMMARY My main setup contains of a laptop running KDE wayland, connected to a monitor via USB-C. The laptop display is configured to be off then the external monitor is connected. _Sometimes_ after I a) open the laptop lid b) disconnect the external monitor the laptop display never comes back and remains black. I can "fix" this by ssh'ing and running `kwin --replace` from other device, but this kills the session and brightness keys no longer work for laptop screen. Rebooting obviously fixes this. STEPS TO REPRODUCE 1. Have a running KDE wayland session with laptop (screen of) and external monitor via USB-C 2. Disconnect the external monitor and hope it reproduces SOFTWARE/OS VERSIONS Operating System: Fedora Linux 42 KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.9.3 Kernel Version: 6.17.8-200.fc42.x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz Memory: 32 GiB of RAM (31.1 GiB usable) Graphics Processor: Intel® Iris® Xe Graphics ADDITIONAL INFORMATION attaching a journalctl log of the event.
