Title:
  Xorg failed to start on boot after upgrade using Nouveau and LightDM

Status in “libdrm” package in Ubuntu:
  Confirmed

Bug description:
  Upgraded via update-manager from 11.10,
  On restart got from tail /var/log/Xorg.0.log

   23.997] (II) NOUVEAU(0): NVEnterVT is called.
  [ 24.661] (EE) NOUVEAU(0): failed to set mode: Invalid argument
  Fatal server error:
  [ 24.661] failed to create screen resources

  The monitor briefly displayed 2 messages
  [drm:drm_crtc_helper_set_config] *ERROR* failed to set mode on [CRTC:6]
  then gave a text login prompt.

  Tried renaming, and also copying /etc/X11/xorg.conf from xorg.conf.default still with same effect
  Tried nomodeset but got a very slow, tiled, stripey desktop, unusable

  Note: can run from liveCD 12.04 with no problem, tried this before
  upgrading

  Note: have to run with option nolapic because of another bug #878031 .
