SUMMARY STEPS TO REPRODUCE 1. Connect an external monitor 2. Go to the screen configuration widgets on the plasma tray 3. Change the internal monitor to the external one RESULT OBSERVED Plasma makes the switch, then restarts with black screen, crash failure and all applications close together EXPECTED RESULT Switches screens only SOFTWARE/OS VERSIONS Operating System: Fedora Linux 40 KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 Kernel Version: 6.10.3-200.fc40.x86_64 (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i5-4200U CPU @ 1.60GHz Memory: 7.7 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 4400
If something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the `coredumpctl` command-line program, as detailed in https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl?
Sorry, I was just deleting the bug report because I found out what was causing it! I was having black screen bugs on plasma randomly and I solved it by applying these 2 environment variables KWIN_DRM_DISABLE_TRIPLE_BUFFERING=1 KWIN_DRM_NO_AMS=1 I removed them because the new plasma 6.1.4 update arrived and I decided to test without them, and that's when the crashes stopped. now I'm monitoring that the black screen bugs have been fixed
That's great! However, KWin still shouldn't crash even with those environment variables set. Can you get a backtrace anyway so we can debug the crash?
Okay, I re-did the steps and the plasma wayland keeps crashing, and when this happens the crash manager appears with the following statement: "Collection of crash information was not completed for unknown reasons. You can try again or close the window." Here is what you asked me, I believe https://paste.centos.org/view/c4d37853
Hmm, that link is broken for me.
