Kubuntu 25.10 Beta - Clean Install To Desktop - Black Screen - nVidia GPU ?

[savantsavior]

Hi,

I installed Kubuntu 25.10 Beta on my desktop just now.
At the end of the installation there is an error?
(something like Installation could not complete)

When booting 25.10 Beta, I get a completely black desktop with the mouse cursor shown?
Running an nVidia RTX 3060 12GB GPU.

Any workaround for the above issue?
Let me know, I am back on 25.04.

A black screen with cursor might mean a Plasmashell crash. If you get krunner when hitting alt-space or alt-f2, then you can use that to open applications like Discover or Konsole, try to update your system to pull in anything missing.

You might also try restarting Plasmashell by entering plasmashell --replace

You can also hit ctrl-alt-f3 (or f4,5, etc) to switch to a tty where you can log in and try updating from there.
