Bug ID: 487134
Summary: Black screen on external display (no wallpaper, no
icons, can't get a context menu on right-click)
Classification: Plasma
Product: plasmashell
Version: 6.0.4
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Target Milestone: 1.0
SUMMARY
The issue description is similar to this one:
https://bugs.kde.org/show_bug.cgi?id=353975
I run KDE on a laptop with external display connected over HDMI. Built-in
display is disabled in "Display Configuration" and external display is
configured as the only one enabled.
Right after booting to KDE black screen is shown on external display. No
wallpaper, no icons, can't get a context menu on right-click. Only task panel
is visible and usable.
It happens randomly but pretty consistently.
As a workaround I use the following command which restarts plasmashell and then
everything is OK again:
kquitapp6 plasmashell && kstart plasmashell &
There are no errors in journal related to KDE, only some warnings but it is
hard to tell if any of those are relevant to this issue. Let me know if any
particular logs can help investigate the issue.
STEPS TO REPRODUCE
1. Have a laptop and external display
2. Connect external display over HDMI
3. Using "Display Configuration" disable built-in display and enable only
external one
4. Reboot
5. KDE is started with black screen
OBSERVED RESULT
Black screen.
EXPECTED RESULT
Wallpaper and icons.
