I updated my perfectly running laptop from 11.04 to 11.10. after the upgrade graphics started to act weird.
It was a heavily modified system, so I thought that was probably the issue.. so I reinstalled. I'm using the xorg-edgers ppa for updates.
Unity 3D does not work... I hear ubuntu's jungle sound and then it just sits there... no icons, just a mousecursor I can move and the background picture.
I have to kill X and log in to Unity 2D to get access to my desktop.

Where do I start looking for the problem? I know it's not the graphics card, it worked fine until the update.
