[Bug 762922] [NEW] Corrupted screen at "Unlocking the disk" phase on an encrypted LVM when using nouveau

 

Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

I'm using Maverick and Natty, both installed using the default LVM
encrypted method on the same hardware. When prompted to "Enter
Passphrase" at the "Unlock the disk" menu the screen is corrupted in
Natty when using the nouveau driver. (see screenshot). This doesn't
happen when using the Intel or the Radeon driver for the appropriate
hardware. I've tested this on multiple computers using AMD and Intel
video cards. Only nouveau fails to display the screen properly.
