I have the same problem in 11.04. System starts and propose me enter login password in console, but I can't do it, because console hidden by violet screen (without Ubuntu logo and progress bar). So I must wait about 10 minutes for gdm start. I can load in recovery mode (and must hope that Ubuntu not hang on load), enter login and password in console and then type "sudo /etc/inid.t/gdm start" (I'll see text on gdm's loading: unable to find users :no seat-id found) and gdm starts. What's wrong. It started when I install video driver.
