Comment 1 for bug 204789

I've got the same problem. The worst part is, I have 2 of these cards, a 256 meg x1650 and a 512 meg x1650 pro. They both kick butt in Vista but I can't even get desktop effects in Ubuntu (Gutsy or Hardy April 11 daily). I've tried installing these drivers from every angle I can find, Synaptic, manually, envy and tried every tip I could find and I always end up with the same white screen.
