Bug ID: 446078
Summary: Attaching/detaching external monitors with Wayland
crashes apps/hides Plasma panel
Product: plasmashell
Version: 5.23.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: Multi-screen support
Assignee: aleix...@kde.org
Reporter: kustod...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
I'm running Arclinux with Plasma 5.23.3 using Wayland on Lenov X1 Carbon Gen 9.
I have an external 4K monitor that is connected via thunderbolt 3 dock. Intel
video driver is used. My displays are set up so that if the monitor (dock) is
attached that is the only active display and the laptop display is off. If I
detach the monitor (dock) the laptop display is used. I have two different
problems when I disconnect the laptop from the dock and when I connect the
laptop to the dock.
When I disconnect the dock all my apps move on the laptop screen and everything
looks to be working, but the Plasma bottom panel is not displayed. I can't see
if plasma crashed or not because everything else works. I have to run: "killall
plasmashell; kstart5 plasmashell" to get the panel back.
Then when I connect the dock back, the laptop screen turns off and the external
monitor turns on, but all the apps, except Plasma crash, or they are killed,
not sure.
Both of these are 100% repro.
Note that I configured different scaling factors for two monitors: Laptop 150%,
and external monitor 100%.
