I have upgraded by following the instructions provided (https://en.opensuse.org/Upgrade) and it went fine except for my Plasma 5 desktop: When I now login into my user account, I get a black desktop:
- I can right-click into it and the menu appears. I might accidently click on a hidden icon and get the respective context menu
- Changing/re-applying desktop configuration does not change anything
- Using a newly created user, Plasma 5 loads just fine. Hence, there must be some previous setting that prevent Plasma from loading correctly.
What can I do to fix this?
