** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  I've got a Thinkpad X40 with a “Intel Corporation 82852/855GM Integrated
  Graphics Device” the driver from xserver-xorg-video-i810 worked for me
  all the time. Yesterday I discovered xserver-xorg-video-intel and
  installed it. When I rebooted my laptop today. Starting X resulted in
  very strange behavior. Most times it just froze with a black screen,
  once pressing any key resulted in strange letters being printed on the
  screen, sometimes it brought up a login screen, even though I use
  autologin, logging in resulted in a frozen black screen.
  
  After changing i810 in /etc/X11/xorg.conf to vesa I was able to log in
  again. I uninstalled xserver-xorg-video-intel and reinstalled xserver-
  xorg-video-i810 and changed vesa back to i810. Now everything is working
  again.
  
  ProblemType: Bug
  Architecture: i386
  Date: Fri Apr 20 13:50:16 2007
  DistroRelease: Ubuntu 7.04
  Uname: Linux fundstueck 2.6.20-15-386 #2 Sun Apr 15 07:34:00 UTC 2007 i686 
GNU/Linux
+ 
+ Impact:  Affects users of intel 855 graphics.  Causes black screen on VT
+ switch (including initial boot up).  As this can prevent use of Ubuntu,
+ it is considered a critical bug and should be backported to Gutsy.
+ 
+ Solution:  Modifies the existing patch 04_fix_hw_restore.diff to
+ conditionalize when pipes are restored so they don't get restored while
+ in VGA pipeline mode.  This driver has been tested by over half a dozen
+ people and has been present in hardy for about a week.
+ 
+ Patch:  http://launchpadlibrarian.net/10316259/xserver-xorg-video-
+ intel_2.1.1-0ubuntu10.debdiff
+ 
+ Steps to reproduce:
+ 1.  Start Ubuntu
+ 2.  Black screen / freeze once X starts.
+ 3.  If not, then switch to vt1 and back, or do suspend/resume
+ 4.  Black screen / freeze
+ 
+ Regression potential:  Low, as this is a small patch that affects only
+ i830-class hardware.  It has been tested on gutsy and rolled out into
+ hardy without any subsequent bug reports
