Hmmm.... Seems bit difficult for you....
Let this driver installation process hand over to built-in "Additional Drivers".
1.
Save a backup copy of xorg.conf in case this process doesn't work (to avoid reinstallation of ubuntu).
$sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup
2.
You need an active internet connection.
3.
You can search for "Additional Drivers" in the Ubuntu Dash Home (Unity).
Or click on wheel button located on top right hand corner of desktop "System Settings" => "Hardware" => "Additional Drivers".
A window will show you up the available drivers applicable for your hardware.
Select "ATI/AMD proprietary FGLRX graphics driver".
Now click on "Activate".
After downloading it will install appropriate driver for your graphics system.
4.
Restart your system.
5.
Now open terminal and run:
$sudo aticonfig --initial -f
6.
Restart your system again.
7.
Search for "AMD" in Ubuntu unity dash home.
8.
Open "AMD Catalyst Control Center".
If you want to change default settings open
"AMD Catalyst Control Center (Administrative)".
9.
EnJoY.
