Created attachment 130664 [details] system and kscreen logs SUMMARY I have 2 external screens that I connect to my laptop using a USB-C dock. 1) When I connect the dock to the laptop, kscreen initially brings up plasma on all screens as expected. 2) But within seconds, the external screens are deinitialized (output stops and they turn off), while the laptop screen is frozen. I've to disconnect the dock to get the laptop screen responding again. 3) When I connect the dock again, this time the external screens are not initalized and I've to manually go and enable them from either the display settings or using the xrandr cli, after which the multiscreen setup works properly. 4) Sometimes, it takes multiple cycles of steps 1-3 to get the external screen to work. I've attached the system logs that shows 3-4 tries before I could get the screens working. All my plasma packages are git master. I'm willing to help debug this and try out patches to finally resolve this annoying bug that I face almost everyday. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.19.80 (kscreen-git r1266.65f342d-1) KDE Frameworks Version: 5.73.0 Qt Version: 5.15.0 Kernel Version: 5.7.11-arch1-1
Seems to be working fine for now.
