Created attachment 142883 [details] gdb-log I am using a G3 3779 Dell laptop with an Acer VG220Q monitor connected via HDMI cable. On a daily basis, the external monitor is connected so that the Acer screen is on the right side. When I turn on a game, watch a video.... I turn off my Laptop screen using screen layout\display configuration widget (on my laptop it is a pair of Fn+F8 keys). When I'm done, I turn the laptop screen back on using the widget so that the Acer is on the right side again. At this point the Plasma crashes and reboots. The same crash is observed when I use System Setting Application (Display Configuration Section) Attached log produced by: gdb plasmashell -batch -ex "set pagination off" -ex "set logging file plasmashell_gdb" -ex "set logging on" -ex "run" -ex "echo backtrace:\n" -ex "backtrace full" -ex "echo \n\nthreads backtrace:\n" -ex "thread apply all backtrace" -ex "quit" Operating System: openSUSE Tumbleweed 20211021 KDE Plasma Version: 5.23.0 KDE Frameworks Version: 5.87.0 Qt Version: 5.15.2 Kernel Version: 5.14.11-2-default (64-bit) Graphics Platform: X11 Processors: 12 × Intel® Core™ i7-8750H CPU @ 2.20GHz Memory: 31.2 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1060/PCIe/SSE2

On wayland, plasmashell crashes for me too when I plug my laptop into an external display, sleep it, disconnect external display, and resume. On resume, plasmashell has crashed. Sorry, no debugging info.
