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

[Steve Langasek]

Hi Alex,

Please run 'apport-collect 762922' from the affected system so we get
additional plymouth debugging information.

Please also boot with 'plymouth:debug' added to the kernel command line
and attach the resulting /var/log/plymouth-debug.log.

Title:
  Corrupted screen at "Unlocking the disk" phase on an encrypted LVM
  when using nouveau

Status in “plymouth” package in Ubuntu:
  Incomplete

Bug description:
  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.
