Okay, after you've installed Linux, if you want to get rid of the basic video drivers provided, you need to install fglrx.
fglrx is a video driver provided by AMD/ATI for the Radeon and FireGL graphics cards for Linux, and there are many other driver options, but this is probably the easiest and it works fine most -if not all- of the time.
Step 1: Downloading
Which version of graphics card do you have? This can be answered by running the command
One of the lines in the output should look similar to this "01:05.0 VGA compatible controller: ATI Technologies Inc RS780M/RS780MN [Radeon HD 3200 Graphics]"
In this case, we would have the Radeon HD 3200 card.
But, that's not all.
Do you have 32-bit Linux or 64-bit Linux?
If you don't know, you're probably using the 32-bit Linux version.

Step 2: Installing
Okay, if you've got the file on your desktop, the command to run it would look somewhat like this.
sudo sh home/michael/Desktop/ati-driver-installer-9-11-x86.x86_64.run
Of course, you've got to change the user name there, and probably the .run file name, but it should work pretty good.
Step 3: Post-install Tasks
Once you're done with that, all you've got to do is run
Hopefully this worked, and if it didn't, I'll try to help out in the comments section!
