Dual Head display on CentOS using ATI Radeon HD 3450

Go to official AMD site to download the official linux driver for this video adapter:
1. install the driver: 
$ sudo sh ./ati-driver-installer-x86.x86_64.run 
#Here I choose custom installation and opt out Catalyst Control Center.
2. Configure the driver after installation and enable dual head display 
$ sudo aticonfig –initial
# if your second display is at the right of your main display
$ sudo aticonfig --initial=dual-head --screen-layout=right

    Thanks very much for this, just what I needed for a Centos 5.9 installation. A couple of typos, the words "to configure driver" are not part of the aticonfig command but belong to the text below starting "and use". Also it should be made clear that you run one of the aticonfig commands, depending on whether you want dual head or not, not both of them. For consistency, the first should also use sudo.

    Also beware if you cut and paste commands from this page. Wordpress has "helpfully" converted double hyphens into en-dashes.
