-- Information about the crash:
- What I was doing when the application crashed:
Launch Kubuntu, then the login screen appears, password OK,
then the usual background appears for a while, with the arrow in the middle, I
can move the arrow, there are no menus;
and then a black screen with the arrow in the center appears and stays without
change. I can move the arrow.
I can open programms with alt+F2.
I have upgraded from 18.04 LTS to version 19.10 without change. I can launch
Ubuntu without problem.
- Unusual behavior I noticed:
this black screen.
The crash can be reproduced every time.
