Bug ID: 484090
Summary: plasmashell dies when creating virtual screens with
xrandr
Classification: Plasma
Product: plasmashell
Version: 6.0.2
Platform: Neon
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: "Manage Desktop and Panels" window
Assignee: plasma-b...@kde.org
Reporter: edua...@bredax.com
Target Milestone: 1.0
SUMMARY
***
In order to use the computer with Meta Quest googles, I have a script that
creates a couple of virtual screens (xrandr) and then calls the App that lets
you remotely connect with the computer.
This week, this process hangs plasmashell as it seems uncapable to start if the
number of phisical screens differ from the total one.

STEPS TO REPRODUCE
1. Open KDE with X11
2. Use xrandr to create a virtual screen.
#!/bin/sh
xrandr --addmode HDMI-1 2560x1600
xrandr --addmode HDMI-2 2560x1600
xrandr --output HDMI-1 --pos 0x0 --mode 2560x1600 --right-of eDP-1
xrandr --output HDMI-2 --pos 0x0 --mode 2560x1600 --left-of eDP-1
3. plasmashell crashes and does not run again until I kill the virtual screens
with
xrandr --output HDMI-1 --off
xrandr --output HDMI-2 --off
OBSERVED RESULT
plasmashell dies and cannot be restarted
EXPECTED RESULT
plasmashell shouldn't die.
