AMD Ati Radeon HD 4870 Drivers on Ubuntu 14.04 [duplicate]

I have a computer with Ubuntu 14.04 installed and I have a Radeon HD 4870 (RV770) video card and I want to install Ati drivers but when I download it says this:

Distro Version entered incorrectly or not supported, use --listpkg to identify valid distro versions

The latest drivers in AMD web doesn't mention my graphic card so I don't know if it works...

Solution 1:

Your card is no longer supported by AMD. AMD now only support HD5000 and above with their proprietary driver.

The good news is that your card is now fully supported by the open source radeon driver.
