How do I install the X.org Radeon/ATI driver?

I recently downloaded version 7 of the Radeon/ATI X.org Driver from this link: http://cgit.freedesktop.org/xorg/driver/xf86-video-ati

My question is how do I compile and install it? I don't like using the offical AMD/ATI Driver.

Ubuntu Version is 12.10

Go into your terminal and type:

sudo add-apt-repository ppa:xorg-edgers/ppa

sudo apt-get install xserver-xorg-video-ati

If you want the stable releases (it would still help if you said what version of ubuntu you're running.):

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get install xserver-xorg-video-ati

To build from git

If you are feeling adventurous, follow these instructions and they should work for you.
