There were over 300 updates when I logged on this morning. All of the updates installed and I shut down until this afternoon. Upon boot, there are only two open windows from my previous session. No wallpaper, no panel, no kickoff menu, and no NetworkManager. If I log out, all I get is a black screen.
Is there a way I can run icewm until I get this resolved?
Logout. If your system is so badly hung that you cannot find a “logout”, then use CTRL-ALT-BACKSPACE (twice) to crash the session. That should get you to a login screen where you can select Icewm.
With auto-login disabled, my system boots to a blank screen. At least with auto-login and I can get to a gui with Dolphin and Konsole open. Everything else is black.
After a lot of trial and error, I saw an error message that said “Plasma is unable to start as it could not use OpenGL 2.” I reinstalled the nvidia drivers and everything is back to normal.
