Bug Description
Possible workaround:
-disable plymouth
-remove v86d
Usually (but not always) if I log out of Ubuntu Natty, the screen freezes with about a 1 inch strip of purple at the top of the screen. Killing x (via ctr+alt+backspace) does the same. Shutting down also has this problem. In all cases I am forced to kill the system.

Hello,
I've got the same bug when the non-free nvidia driver are used. Actually, after some logout/ reboots/ shutdown (without the driver installed) I've got no problem. I suppose this is the driver for nvidia 64bits but I'm not sure.
