Bug ID: 473220
Summary: Screen layout not correctly restored when displays
wake up and one screen has been deactivated previously
Classification: Plasma
Product: plasmashell
Version: 5.27.7
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-multiscreen
Assignee: plasma-b...@kde.org
Reporter: malted....@gmail.com
CC: aleix...@kde.org, notm...@gmail.com
Target Milestone: 1.0
SUMMARY
I'm have 4 displays attached to my GPU: 3x Displayport for the screens in my
office and 1x HDMI with a long cable to the TV in the next room. (So I can
watch movies, play games in the living room in the evening)
When working on my PC I deactivate the HDMI screen as I can't see the TV and
don't want to have windows, mouse etc "vanish" to a different room.
But when leave the PC for a break and return with the session locked and the
displays put into sleep, and unlock the session, the screen/desktop
configurations are completely messed up.
STEPS TO REPRODUCE
1. Run Plasmashell Wayland with 4 screens (haven't tested with 3 or 2, but
might work as well)
2. Configure backgrounds, control bar etc. to your liking
3. Deactivate one screen in the System Settings (4->3 screens (or 3->2 screens
or 2->1 screen))
4. Let the Screen Lock activate and the Screens go to sleep (Energy Savings
Settings)
5. Make some inputs on the PC to wake the screens up and unlock the session
OBSERVED RESULT
The Desktop is not restored to its state before locking/screens turned off. The
screens and their configuration might be shifted to different physical displays
or completely missing.
Running "plasmashell --replace &" in the terminal does restore the correct
configuration.
When all screens are activated, the correct desktop configuration is always
restored.
EXPECTED RESULT
Even when screens are turned off, the configured desktop layout should be
restored.
