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

[Jane Atkinson]

Colin:
I don't know what happened the last time. Any "workaround" would have been accidental.

Anyway, I've taken another shot which I've attached as videoinfo2.jpg

I'm finding it difficult to get a shot in which the numbers are really
readable, so if any of them need to be written down and posted, I can do
that.

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.
