Hello Linux Geeksters. As you may know, the AMD Catalyst 14.4 RC drivers for Linux have been recently released, coming with support for Ubuntu 12.04.4 (no information about Ubuntu 14.04 Trusty Tahr yet).

System requirements:
- Xorg/Xserver 7.4 and above (up to 1.15)
- Linux kernel 2.6 or above (up to 3.13)
- glibc version 2.2 or 2.3
For information about this release, see the changelog.
In this article I will show you how to install the AMD Catalyst 14.4 RC drivers on Ubuntu, Linux Mint, Elementary OS, Debian, Fedora, CentOS, OpenSUSE, Mageia and OpenMandriva.
Because the drivers are not available via any repository, we have to download the the zip archive from the official site, extract it, set execution permissions:
Download AMD Catalyst 14.4 RC drivers
$ unzip ~/Downloads/linux-amd-catalyst-14.4-rc-v1.0-apr17.zip
$ cd fglrx*
$ sudo chmod +x amd-driver-installer*.run
Kill the display manager, which can either be: kdm for KDE, gdm for Gnome, lightdm for LXDE and XFCE (i think), mdm (for Linux Mint):
$ sudo /etc/init.d/kdm stop
OR:
$ sudo /etc/init.d/gdm stop
OR:
$ sudo /etc/init.d/lightdm stop
OR:
$ sudo /etc/init.d/mdm stop
And finally, run the AMD Catalyst binary file:
$ sudo ./amd-driver-installer*.run
