Title:
  Ubiquity freezes during nfs-based desktop install from recent live
  destkop images on physical hardware

Status in “xserver-xorg-video-intel” package in Ubuntu:
  Confirmed

Bug description:
  I'm attempting to do automated installs of raring live desktop images
  over a network on physical machines using a combination of cobbler and
  NFS.  Since December 20, these installs have failed on i386 and amd64.
  DI installs from current server images work, and old images work fine
  for ubiquity installs.  At some point during the installation, video
  stops updating.  I started an install with an active SSH server and I
  was able to run apport that way, but the local video still does not
  update.  This is on a machine Canonical's magners lab.  I've looked at
  lp:1080701 but removing all partitions before installing doesn't seem
  to help.  Please let me know what other information I can gather.
