In 12.04 I used the official driver downloaded from amd.com which came with amdconfig but now in 14.04 the official driver is buggy so I just use the Ubuntu Official Drivers which works even better because they beefed up the original driver. The Ubuntu driver doesnt come with the terminal command amdconfig which allowed me to tweak/overclock my graphics card. How can I install it without having to install the original AMD driver?

Additional Information:

-I only use x.org drivers becuase it's opensource therefore more stable rather than the proprietary fglrx driver

-I do not use procrams like amdoverdrivectrl or atioverclock because they are not as stable and advanced as the terminal command
