BEFORE YOU PROCEED NOTE: For Ubuntu 16.04 LTS and above, the AMD Catalyst or fglrx driver is no longer supported by AMD, or in Ubuntu. If you have an AMD GPU and wish to run any Ubuntu version 16.04 LTS or newer, there are two open source driver options: Radeon or AMDGPU. The AMDGPU-PRO driver provides the open source AMDGPU driver and a proprietary overlay.
Newer AMD GPUs designed with GCN technology (Graphics Core Next) should use AMDGPU or AMDGPU-PRO, while older AMD GPUs should use Radeon. For details on which GPUs require Radeon, please see the or execute at a terminal: man radeon 2.
How To Install Ati Drivers Ubuntu 12.04
Introduction By default Ubuntu uses the open source driver for cards manufactured by AMD. However, the proprietary fglrx driver (known as AMD Catalyst or AMD Radeon Software) is made available for those who would like to use it. The instructions on this page advise on how to install and use fglrx. If you encounter a bug with these closed-source drivers, you are welcome to file a report via Launchpad. However, if the bug is determined to be with fglrx, this may only be fixed by AMD, as they are the only ones with access to the source code. Before you get started The first thing to check for when you consider using the fglrx driver is whether your AMD graphics card is supported.
How To Install Ati Radeon Driver In Ubuntu
Enter your graphic card details. You may check this at the terminal: lspci -vvnn grep VGA.
Identify whether your AMD graphics card model series is supported by the fglrx driver. If the search returns the latest version of the Catalyst driver, then proceed to the next section. If the search returns a legacy version, you may have to use the open source driver. NOTE: If you are switching from another OEM's hardware, NVIDIA for instance, you must uninstall the driver for that hardware before installing the AMD driver.
Installation via the Ubuntu repositories Ubuntu offers the following fglrx drivers that are supported up to Ubuntu 14.04:. Precise only. The easiest way to install binary drivers is to use the built in Additional Drivers manager in Ubuntu. After the fglrx driver is installed, reboot your system and login. To check whether the fglrx driver is working, open a terminal and type: fglrxinfo If fglrx is installed and working well you should see an output similar to: fglrxinfo display::0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 4300/4500 Series OpenGL version string: 3.3.11399 Compatibility Profile Context 4.1. Installing via the command line For users who find that the Additional Drivers method does not work, please file a bug report on Launchpad about this.
Once done, the driver may also be installed from the Ubuntu repositories using the terminal. (Note: If your machine has hybrid Intel/AMD switchable graphics, please consult the Ubuntu Forums thread first and refer to the section titled 'Manually installing Catalyst 13.4, special case for Intel/AMD hybrid graphics' in this wiki. At the time of writing, the method described below MAY NOT WORK for Intel/AMD switchable graphics. If you have an Intel/AMD hybrid, it is advisable to wait until further instructions are available). Save a backup copy of xorg.conf in case this doesn't work.
Sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.BAK. Remove/purge current fglrx and fglrx-amdcccle (If you have used a method outside of aptitude, apt, Software Center or Synaptic, follow the other party's instructions for removal).
You will need to deliberately remove both the normal and -updates versions in recent releases of Ubuntu because it seems that attempting to remove one installs the other: sudo apt-get purge fglrx. Reboot.
