ubuntu install amd catalyst

SkyHi @ Monday, August 20, 2012

ATI Radeon™ HD 3450 GPU on Ubuntu 12.04

Manually installing Catalyst 12.6, special case for Intel/ATI hybrid graphics

WARNING: Using a method other than described in the manual instructions section above by creating a .deb file can lead to extreme difficulties. Be sure to take note of the instructions for uninstalling the driver at the end of this section, since the driver must be uninstalled using the amdconfig utility.
This method is NOT RECOMMENDED in general, but has been found by some users to make the chore of getting Intel/ATI hybrid graphics to work less difficult.
This method PROBABLY WILL NOT WORK for HD 5xxx or earlier cards. It has been shown by some users to work only with 6xxx and 7xxx series cards.
1. Save backup copy of xorg.conf in case this doesn't work.
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.BAK

2. 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.)
sudo apt-get remove --purge fglrx fglrx-amdcccle

For some users, the fglrx-updates and fglrx-amdcccle-updates packages do not work. If you attempted to install them, also do
sudo apt-get remove --purge fglrx-updates fglrx-amdcccle-updates

3. Reboot
4. Download the driver found at the AMD/ATI website
5. Navigate to the directory to which the file was downloaded
cd /path/to/file

6. Make the .run file executable, using the 12.6 driver as an example (modify as needed for future versions. Note that the name of the .run file is for ILLUSTRATION only and you must be sure that you type the name of the actual file correctly.)
sudo chmod +x

7. Execute the .run file
sudo ./

Be sure to click "Install Driver" as shown: 
8. Create a new xorg.conf
sudo amdconfig --initial

9. Reboot.
10. To confirm the drivers are working open a terminal and type:

You should get an output similar to the following:
display: :0  screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 6300M Series
OpenGL version string: 4.2.11733 Compatibility Profile Context

11. The Catalyst Control Center should now offer a choice between the integrated Intel graphics and the dedicated AMD/ATI graphics. To switch, select the graphics you want to run. Because the change is not dynamic, a reboot is required.
12. To uninstall after installing using this method, you MUST use the amdconfig utility:
sudo amdconfig --uninstall
