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.

DistroRelease: Ubuntu 7.04

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.
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
