[Bug 897921] Re: Corrupted grub screen in Precise alpha1

[Colin Watson]

Hm, are you sure you didn't run that 'videoinfo' command with some
workaround or other in place?  Ideally, it would actually be most
helpful to get that output when GRUB has started with the screen in this
corrupted state.

Title:
  Corrupted grub screen in Precise alpha1

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  I found this during ISO testing. It is somewhat similar to bug #701111
  (marked "fix released"), except that I'm using different hardware.

  Hardware is
  VGA compatible controller [0300]: VIA Technologies, Inc. CN896/VN896/P4M900 [Chrome 9 HC] [1106:3371] (rev 01)
  Subsystem: ASUSTeK Computer Inc. Device [1043:81ce]

  Output of lspci -vn is attached.

  When I boot, the grub screen will appear to flash between appearing in
  the normal position and showing the left edge in the middle of the
  screen. Sometimes, it flashes backwards and forwards between the two.
  I've also attached a photo of the screen.

  Grub itself behaves normally; it's just the display that's unstable.

  Uncommenting the line

  GRUB_GFXMODE=640x480

  in /etc/default/grub and running "update-grub" fixes the problem, but
  of course renders the screen in a larger font.
