After installing ROS2, for some reason, the graphical session stopped starting. When loading, I get a black screen and a cursor. I tried to switch to console mode and execute "startx", after a long boot, a part of previously opened windows appeared, but without the taskbar, etc. When I try to execute "kstart5 plasmashell", I get the following:

Solved "apt update" and "apt full-upgrade"...

Go with Strg-Alt-F2 to another login Screen. login
then

Code: Select all

 sudo systemctl restart sddm

Does it work?
If not try to install another system kernel
