Intel 855GM Graphics Card not working in Ubuntu 7.10

If you have an Intel 82852/855GM Integrated Graphics Device in your laptop, you might (surely) get problems with Ubuntu 7.10.
To find out if you have this card, try this:

$ lspci |grep Display
Display controller: Intel Corporation 82852/855GM Integrated Graphics Device (rev 02)

With the default intel driver, your system might freeze with a blank screen after loading the xserver, or after switching to a tty.

See Launchpad Bug# 108056.

The current xserver-xorg-video-intel release does not fix the problem. There are some patches, but the easiest way is this workaround:

• Remove (uninstall) the xserver-xorg-video-intel package
• Reinstall the xserver-xorg-video-i810 package
• Change your /etc/X11/xorg.conf. Change every:

Driver          "intel"

to

Driver          "i810"

You can also try to change the driver with the “Screens and Graphics” tool. But I am not very positive about this tool. It didn't change the driver in my case after trying 3 times. And never trust the “Test” button (on Intel and ATI cards…).
