Cannot log on to desktop.
I recently upgraded from 11.4 to 12.1 and now I cannot logon to me desktop. It shows me the login screen and logs me in to an empty desktop with just mouse functionality. I was getting an error that said that it was unable to load session "GNOME". So I though maybe it was because it my graphics card was too old and simply could not handle gnome 3, so I went into yast2 and removed all the packages that I could see that referenced gnome 3. It now get psat the error message but still drops me into a blank desktop with just the mouse. I am not sure what borked my system so any help would be much appreciated. Thank you all.
