Stuck on 800x600 resolution Dell 1100

[miocene]

I was having some problems with my last install of Xubuntu so I did a clean install of Ubuntu 8.10.

All has gone well except I can't increase the screen resolution beyond 800x600. This means only about 2/3 of my screen area is used.

My comp has integrated intel graphics.

Bump!

Here is my xorg.conf file if this is any use:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

It seems that it doesn't know my monitor or video device. My video device is definitely Intel Extreme integrated graphics, I thought ubuntu installed it fine!

Xwindows has the ability to change the video mode on the fly with hotkeys. What happens if you press [CTRL + ALT + +] ?
