Bug ID: 460676
Summary: Broken desktop environment after multi monitor power
on
Classification: Plasma
Product: plasmashell
Version: 5.26.0
Platform: OpenSUSE
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: Desktop Containment
Assignee: plasma-b...@kde.org
Reporter: jer...@gmail.com
CC: notm...@gmail.com
Target Milestone: 1.0

Monitor Layout
After powering on monitors the shell is broken with Nvidia driver from 5.26.0
version. The panel is in the middle of the screen and one of the monitors won't
wake up. Kscreen configuration is corrupted and must be removed in order to
make the monitors behave correctly again.
STEPS TO REPRODUCE
1. Wait until monitors are shut down due to energy savings (suspend or
hibernation are not necessary)
2. Lock screen does not affect the bad behavior.
3. Move mouse or press any key in order to power on monitors.
OBSERVED RESULT
I have 3 monitors and one of them will not power on again. Kde panel appears in
the middle of the screen and mouse click target acts as if graphics where in
the original position. Kscreen config in '.local/share/kscreen' must be deleted
in order to be able to reconfigure monitor layout after restart.
EXPECTED RESULT
After moving mouse or pressing any key monitor layout is correct after powering
on and no graphic corruption appears. If lock screen is active, password is
required in order to enter the session again.
