Method 2: Generating/Installing Ubuntu packages for the newer 8.23.7 drivers in Breezy Badger

Important Warning: Installation of this driver requires removing the restricted-modules package in order to work. That package includes drivers for madwifi (Atheros wireless cards), nvidia cards, and a handful of other devices. I provide a work-around for the madwifi drivers, but you need to perform it before removing the restricted modules (jump to end of this this post).

When running the dpkg-reconfigure command you should answer the questions that you know and take the defaults for the rest. You might want to say no to the monitor detection--it has caused X-Windows to crash for some people.

Remove existing fglrx driver

Remove Breezy's included drivers if they are installed:

sudo apt-get remove xorg-driver-fglrx
sudo apt-get remove fglrx-control
sudo apt-get remove linux-restricted-modules-$(uname -r)
sudo dpkg-reconfigure xserver-xorg #select the "ati" module

Reboot.

Installing the new driver

Download the ATI driver installer: Click here

Change to the download directory. Make sure that you have the universe and multiverse repositories enabled in /etc/apt/sources.list before doing these steps. Sample sources.list.

Install necessary tools:

sudo apt-get install gcc-3.4 module-assistant build-essential
sudo apt-get install fakeroot dh-make debconf libstdc++5 gcc-3.3-base

Create .deb packages:

chmod +x ati-driver-installer-8.23.7-i386.run
LANG=C LC_ALL=C ./ati-driver-installer-8.23.7-i386.run --buildpkg Ubuntu/breezy

Install .deb packages:

sudo dpkg -i xorg-driver-fglrx_8.23.7-1_i386.deb
sudo dpkg -i fglrx-control_8.23.7-1_i386.deb
sudo dpkg -i fglrx-kernel-source_8.23.7-1_i386.deb

Remove any old fglrx deb's from /usr/src/:

sudo rm /usr/src/fglrx-kernel*.deb

Compile the kernel driver:

sudo module-assistant prepare
sudo module-assistant update
sudo module-assistant a-i fglrx

Update the xorg.conf file:

sudo aticonfig --initial

Reboot.
