I have Ubuntu Maverick and after some tweaking with Ubuntu tweak I lost the ability for unity to start past the logon screen and name popups. After that I get an error saying unity cannot start..No required devicerdetected for unity. I tried to download gnome3 to bypass the whole unity thing and that didn't start either. What can i check to see what's wrong with Unity? I am able to work only from the terminal screen. I used a live cd to test the system and all the videos drivers were listed passed except for the xrandr-cycle test. thanks in advance!
