Bug ID: 475922
Summary: kwin_wayland freeze loop on DisplayLink connection
Classification: Plasma
Product: kwin
Version: 5.27.8
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: sandw...@archworks.co
Target Milestone: ---
SUMMARY
Kwin_wayland freezes if Monitors are plugged in over a DisplayLink connection.
It sometimes works for a second then freezes and sometimes reinitialize the
monitors in loop.
The laptop in Use is a Lenovo ThinkBook 14 G3 with an AMD GPU, the Monitors are
connected to a Lenovo Docking station, that connects over USB-C and the
DisplayLink protocol to the laptop.
The following kernel drivers were needed on X11 "evdi" and "displaylink"
This matter is important since Plasma 6 is coming and many Users utilize
DisplayLink docks in a Work environment.
I have two monitors:
1. 1920x1080 75hz Scaling 100% (Main)
2. 1920x1080 75hz Scaling 100%
STEPS TO REPRODUCE
1. Start Plasma Wayland Session
2. Connect Monitors with the Docking Station
3. Plug in the Docking station to the laptop using DisplayLink
OBSERVED RESULT
Display turn on, and sometimes work for 1-2 seconds, then the image gets
static.
Laptop Screen still responsive, but most of the time the session freezes.
Sometime
