Title:
  Can't switch to console mode when booting from grub2

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: xorg

  In Karmic, I can no longer get a console screen with CTRL-ALT-Fx, eg
  CTRL-ALT-F1. The screen changes mode to a black screen filled with
  random coloured pixels and (on some consoles) a flashing single-pixel
  cursor midway across the screen (pressing ENTER changes the screen
  somewhat, so it seems to be a screen resolution problem).

  It used to work until quite recently in Karmic and it works in Jaunty
  with the same nvidia drivers.

  This looks similar to bug #129910. modprobing the modules suggested
  there (eg vesafb) doesn't help, though.
