I had got the exact same problem. I found that if you edit xorg.conf, go under device, and look for the bus id, it is something like 0:4:0
where it should be 1:0:0 -- nvidia binary drivers don't work anymore in Edgy (regression) https://launchpad.net/bugs/67271 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
