    Segmentation Fault when trying to install ATI drivers


    Hello guys. I recently installed Ubuntu Lucid 10.04 64-bit on my desktop.
    I was trying to install the ATI Drivers for my graphics card (ATI Radeon HD5850) by using the guide:
    Search on google for "Ubuntu Lucid Installation Guide", from wiki.cchtlm.com
    Unfortunately I cannot post links yet.

    I was using the manual install guide. I followed the guide step by step and everything went OK without any errors, until I get to this step: fglrxinfo

    And it returns with a "Segmentation Fault"

    Any thoughts on this? Help would be greatly appreciated

    Did you try installing the drivers provided by Ubuntu? System>Administration>Restricted Drivers or something like that. From the link you mentioned. See the section titled "Restricted Drivers Manager".
    It also says
    Test your installation

    Reboot or fglrxinfo gives an error message. From a terminal window (minimal install must first start x-terminal with 'xinit'), type

    I just uninstalled the drivers I tried to get to work, and installed the drivers provided by Ubuntu instead. (System>Administration>Hardware Drivers)
    and it tells me that I have the ATI/AMD proprietary FGLRX graphics driver installed, and that the driver is Activated and Currently in use.

    I suppose I'm all set up then? Any way to double check that the drivers are actually in use?

    I have never used an ATI card so I am not certain this works but it certainly won't hurt to try.
    Code:
    sudo glxinfo |grep -i rendering
    Try running glxgears
    Code:
    glxgears
    This not much more than a tool to show that opengl is working and the frames per second...it's not exactly a benchmark or anything.

    Tried both of them, this is what I got

    frederik@frederik-desktop:~$ sudo glxinfo |grep -i rendering
    [sudo] password for frederik:
    sudo: glxinfo: command not found
    frederik@frederik-desktop:~$ glxgears
    The program 'glxgears' is currently not installed. You can install it by typing:
    sudo apt-get install mesa-utils
