AMD ATi Radeon HD 6870 drivers not working

Need some help with this. I've searched for a few hours and found no answer that worked for me.

When I try to install my drivers I get

One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver. Optionally, run the installer with --force option to install without the tools. Forcing install will disable AMD hardware accelleration and may make your system unstable. Not recommended. See /usr/share/ati/fglrx-install.log for more details.

So I checked that log and it gave me

Supported adapter detected. Check if system has the tools required for installation. fglrx installation requires that the system have kernel headers. /lib/modules/3.8.0-6-generic/build/include/linux/version.h cannot be found on this system. One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver.

Ok first we have to remove all your previous installations.

In the terminal run:

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

then

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-get install linux-headers-generic

now go to dash, open software sources, go to additional drivers tab. You should see the catalyst 13.2 beta 3 driver, activate it.

when you're done, in the term run:

sudo amdconfig --initial -f

reboot.

Download the driver from here :

To install refer to the second part of the answer on /questions/18747/.

I don't use fglrx drivers because they're not the same ones issued by AMD, and given this is all proprietary, then there's no point not going to the source instead of Xorg.
