Go to
www.ati.com, from the menu select "Drivers and Software" and in the dropdown menu select Linux. Choose your graphics card. Follow the instructions.
You will not go the ./configure && make && make install way, since these commands are for compiling from the source code. Since the drivers are proprietary, you will receive a binary driver which you will have to run - something like:
Code:
sh ati-driver-installer.run
