  • Radeon HD 6750 / 6620

    I have been going crazy trying to figure why I can't get these drivers to work. When I go to hardware drivers under system-administration, it tells me I have fglrx installed, but whenever I try to change my graphics settings on my desktop, it tells me I cannot. In terminal, the command fglrxinfo gives me a segmentation fault, and I cannot even guess what that might mean. I installed(attempted to) the driver using the commands

    $ sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
    $ sudo apt-get update
    $ sudo apt-get install fglrx

    I am running ubuntu 10.04-LTS on an hp dv7-6165us, which has a dedicated radeon 6750 and an on board 6200 or something which is part of the amd a8. Any and all help would be greatly appreciated.

    Thanks.

    try running:

    Code:
    lsmod | grep -i fglrx
    and:

    Code:
    dmesg|grep -i fglrx
    lsmod displays the list of kernel modules currently loaded and dmesg displays kernel messages so one of then should show fglrx somewhere in the output. if not, fglrx is most likely not being used at all.

    actually, an easier way to check is:

    Code:
    glxinfo|less
    which should display OpenGL info. look at OpenGL renderer string and it should ATI/AMD.
