I had installed the drivers suggested by jockey-gtk so I had to uninstall them first using
jockey-gtk. And restart the machine.
These are the step by step procedures
- Uninstall any graphics drivers already installed and reboot the machine.
- Now install the drivers using this command
sudo apt-get install fglrx-updates fglrx-amdcccle-updates
- Initialise aticonfiguration
sudo aticonfig --initial --input=/etc/X11/xorg.conf
- Restart the system

I'm loving it! If you need to install Compiz, here is the Stackoverflow question that I followed: http://askubuntu.com/questions/86977/how-to-correctly-enable-desktop-cube-in-unity-3d
I have decided to stick to Ubuntu although I have been using Fedora for a long long time. But Fedora had its vices like the infamous SELINUX, which always caused troubles. I am loving the Ubuntu Software Centre and Ubuntu One storage too :).
