I decided to try using mythbuntu to simplfy getting mythtv to work. so I went to synaptic and installed the mytbuntu-desktop meta-package. I logged out, checked the mythbuntu session, then tried to log back into my gnome session. I heard only the "bump-ba-dump" part of the startup sound then it chashed. I tried Gnome-failsafe, but nautalus wouldn't start. I fixed that by killing the procces it recomended to kill, then restarting nautalus. I then decided to try Gnome without failsafe, same. Then I went back to failsafe, and got only sound with completely blank brown screen with a working mouse cursor. I am now typing this from my KDE sesion, with is the only one that works other than the mythbuntu session.
