The third time i logged in i switched to tty1 and the login screen showed for an instant. The crash can be reproduced every time. -- Backtrace: Application: Plasma (plasmashell), signal: Aborted Using host libthread_db library "/lib64/libthread_db.so.1".

Without apparent reason now i can login normally. The desktop runs in tty2 normally. If i change to tty1 the first time it shows the display manager with login option for an instant and then turns into black screen, the succesive times i turn to tty1 only shows black screen. I don't know if this is the expected behavior. The pointer continues to seem bigger than usual over the desktop but normal over windows. I forgot to point that the environment is a Fedora 31 virtualbox guest on Windows 10 host.

Cool, thanks.
