Comment 23 for bug 726496

I have this exact problem. I am using a GeForce 7300 LE. This seems to affect a lot of laptop users, but I have the desktop version of this card.

The unity_support_test passes completely, but the desktop hangs if I load either Unity or Classic Gnome with Effects. I had no video problems on multiple prior releases, but discover then which I upgraded from 10.10 to 11.04.

There are no errors in Xorg.0.log or anywhere else that I can find. What information can I provide that would be helpful for debugging?
