Comment 3 for bug 712630

  I chose Close, instead of Change session, since I could not see what Change session would mean. I got the same results, anyway. As an experiment, I tried switching to a virtual console and enabling an nVidia proprietary driver. I hoped that a reboot would then let me run Unity or something. After the reboot, I never see anything but a blank screen and cannot bring up virtual consoles again.

 I got these results on a system with a Matrox G400 video card and on one with a nVidia Ti4200.
