I installed 11.2 from the live install, choosing Gnome. I ran the updates, then uninstalled several pieces of software that came pre-loaded.
Then I noticed that the menu Gnome editor didn’t work all of a sudden. I noticed that the “desktop background” right-click didn’t bring up the appearance preferences dialog. Then I couldn’t add anything to the panel. I never logged in as root or anything like this, or did anything other than install updates/uninstall a few applications (Evolution, etc)
So, I rebooted.
Then, instead of getting into Gnome, IceWM login screen loaded. Then IceWM. I guess this is a fail-safe in case the DE doesn’t load - and its good thinking!
But, does anyone have any ideas what could have caused this? (Gnome, Metacity/Compiz, GDM, Updates?)
I am not an expert on GNOME, but from IceWM, you can still run Yast and then Software Management. I would search on GNOME and perhaps reinstall the important gnome packages that you might have removed.
