Description Nils 2020-09-23 07:30:38 UTC
SUMMARY

Every time I boot my laptop with an HDMI connection to my screen (set as principal AND the laptop screen is disabled), I got this issue where the wallpaper is black and if I try to right click on it, nothing happen. 

STEPS TO REPRODUCE
1. Boot your laptop with an external display set as main and laptop screen disabled
2. login

OBSERVED RESULT

Black screen, right click on wallpaper bring nothing

EXPECTED RESULT

Wallpaper is loaded, right click bring the popup options. 

SOFTWARE/OS VERSIONS
Linux: 5.8.10-arch1-1
KDE Plasma Version: 5.19.5
KDE Frameworks Version: 5.74.0 
Qt Version: 5.15.1

ADDITIONAL INFORMATION

A way to solve this is to go to display configuration, set another resolution for the external monitor. It then load the wallpaper and the right click works again. I then choose the normal and expected resolution and I am all good to go. 

I can upload a GIF showing the issue if it helps? I can also put some warnings from journalctl if need be?

What happens if you manually run `plasmashell` from a terminal?
Comment 2 Nils 2020-09-23 10:02:00 UTC
It output nothing and does nothing. The issue is still there.
Comment 3 Nils 2020-09-23 10:06:15 UTC
Typing `plasmashell --replace` in krunner works however?
Comment 4 David Redondo 2020-09-23 10:08:44 UTC
That means that we have a plasmashell running but something is wrong with the actual desktopview. When you change the resolution I think we are getting a new Containment
Comment 5 Nils 2020-09-23 10:46:19 UTC
Could I provide something in order to know what's wrong with the desktop view?

Definitely reminds me of Bug 426496.

Yes indeed. It's quite new and it feels related to the Qt upgrade. Probably a duplicate.
