845G/855G/865G/915G/945G chipset installation workaround on Breezy preview

The drivers for the i915 (or similar) chipset are not available neither in Hoary, nor in Breezy (preview).

As a result, GDM might not be able to reach the maximum resolution.

Steve Tomljenovic provides a very nice workaround for this, called 915resolution.

It is available from: http://www.geocities.com/stomljen/

All I had to do was:

  1. Download 915resolution

  2. run "915resolution -l" as root

  3. Pickup an unused resolution ('3c' for me)

  4. run "915resolution 3c 1400 1050 32" as root

  5. Edit /etc/X11/xorg.conf to add:

Option "ForceBIOS" "1920x1440=1400x1050"

As a result, the /etc/X11/xorg.conf looks like:
