Description AndreasH59 2021-09-23 06:43:13 UTC
I hope this is the right section. 

I have a triple screen setup here. After almost every boot now i have a "zombie" desktop screen, its black but i can drag a window over it, mouse pointer is there, but no right click menu and no wallpaper.

Turning the monitor on and off does not change that. 
Loging off/on or a plasmashell restart brings it back to normal.  


STEPS TO REPRODUCE
1. boot manjaro with triple screens ;)
2. 
3.

KDE Plasma second Desktop-wallpaper stays black & no menu

i’m running Manjaro KDE with two monitors.
Since weeks the second monitor doesn’t show a wallpaper, only black screen.
I can’t right click on this second desktop and get into the rightclick menu to do anything.
But i can drag windows on this second screen and work like normal without any graphics issues. See attached file (kde-black screen.jpg)

Once every 20th reboot i get both wallpapers and it works, but most of the time not.
Unplugging the second monitor helps sometimes, most of the time bug occurs again after reboot.
Switched Kernels from LTS, 5.12, 5.13, 5.14, reinstalled whole system, always same issue.

I think this is **not** a duplicate. 

Bug 427861 is "just" a reset of settings. Your settings go back to default but at least, the desktop works, it has a (default) wallpaper and you can have a context menu when you right-click.

Here in this bug, what we call a "zombie" desktop screen is a desktop where the wallpaper is unset (black), without any trace of Plasma Desktop. You can't even right click on the desktop. You can just drag windows on the "zombie" desktop.

I'm not even sure the "zombie" desktop loses its settings, we would have to investigate. But it seems to be a temporary glitch because it does that one out of 5 startups.

Also, for me it only does that on my second monitor.
