FLGRX (AMD Catalyst) driver issues in Ubuntu 12.04

Solution 1:

I suggest two things

1 In a terminal type the following

fglrxinfo

This will tell you 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

If not it has not installed properly and I would follow the advice on the Ubuntu ATI page here Ubuntu ATI site

I usually always install the ATI drivers in the terminal with the following command

sudo apt-get install fglrx fglrx-amdccclete

You may also need to reinstall the updates again:

sudo apt-get install fglrx-updates fglrx-amdcccle-updates

It can be a pain I know from experience. Sometimes I have had to go back the beginning by cleaning out fglrx (sudo apt-get purge fglrx*) and starting afresh.

Let us know how you get on
