Bug ID: 459085
Summary: Second monitor is disabled in Displaylink setup under
Wayland
Product: kwin
Version: 5.25.5
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: alexander.reinho...@kdemail.net
Target Milestone: ---
SUMMARY
I am using a TUXEDO Computer PULSE 15 (gen 1, specs see down below) laptop with
an i-tec Displaylink adapter (TUXEDO Office Hub).
After the upgrade from Plasma 5.24.5 to 5.25.5, my external monitor is disabled
when starting Plasma under Wayland. Also, it seems that the display is entering
an infinite loop of crashes and attempts to recover. Strangely, changing once
into the console (e. g. CTRL+ALT+F3) stops this loop. However, the external
monitor is never activated / recognized.
So, from my point of view, this is a regression compared to 5.24, since my
setup worked back then.
Using Xorg is currently unfortunately not an option, since then everything is
slowed down to a few FPS.
Maybe I can provide a screenshot of the config page with the error message
shown, but due to the continuously crashing KWin, it's quite hard to do
anything...
STEPS TO REPRODUCE
1. Attach the laptop to the Displaylink adapter
2. Log in with the Wayland session
3.
OBSERVED RESULT
The external monitor is not recognized / activated and the display / KWin
enters an infinite loop of crash and recovery.
EXPECTED RESULT
Working display setup.
