First check supportable driver for your graphics card. http://support.amd.com/en-us/download/desktop?os=Linux+x86 See tab Supported Products.
Note that is supported by Linux kernel 2.6 or above (up to 3.19)
If your video card is supported you can proceed with the installation.
NOTE: To successfully install the official AMD Catalyst ™, you must uninstall any third-party drivers for graphics adapters that are currently installed in a Linux system.
To delete all third-party drivers for your graphics adapter, perform the following steps:
Open a terminal, run the commands to remove the drivers:
sudo sh /usr/share/ati/fglrx-uninstall.sh --force
After this, download the driver from the manufacturer's website, at the following address - support.amd.com. At the time of writing, the latest version of the driver was 15.2, unpack the archive, inside of which we see a file with the extension .run.
Installing the driver:
Open a terminal in the directory in which you unpacked the archive. Run the commands below
sudo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev debhelper lib32gcc1
udo apt-get install cdbs dh-make dkms execstack dh-modaliases linux-headers-generic libqtgui4 xserver-xorg-dev debhelper
Give the right to start and run the install:
sudo chmod +x amd-driver-installer-15.20.1046-x86.x86_64.run
You can then install the driver. But to be safe, I advise you to close a graphics session and continue with the installation in console:
sudo service mdm stop
Enter your username and password.
Now we can start the installation:
sudo sh amd-driver-installer-15.20.1046-x86.x86_64.run
Create a config file for the video driver::
sudo amdconfig --initial -f
Now you can restart the computer:
