    Ubuntu video won't function properly

    Hi, I'm new to ubuntu. I heard it was possible to run Ubuntu on my system configuration; I have an AMD Athlon x2 CPU, an ATI 3870 Video Card, and 2 GB of ram. The problem is, I also have an onboard card that Ubuntu keeps recognizing as the primary video device.

    I followed a guide for installing the xorg video drivers, and all went well, until I restarted. It gives me an option to run in low graphics mode, which only works half the time. fglrxinfo says that GLX isn't functioning properly, and I already correctly modified my xorg.conf according to:
    http://wiki.cchtml.com/index.php/Ubu...allation_Guide

    Here's my xorg.conf:

    Code:
    # xorg.conf (xorg X Window System server configuration file)
    #
    # This file was generated by dexconf, the Debian X Configuration tool, using
    # values from the debconf database.
    #
    # Edit this file with caution, and see the xorg.conf manual page.
    # (Type "man xorg.conf" at the shell prompt.)
    #
    # This file is automatically updated on xserver-xorg package upgrades *only*
    # if it has not been modified since the last upgrade of the xserver-xorg
    # package.
    #
    # If you have edited this file but would like it to be automatically updated
    # again, run the following command:
    #   sudo dpkg-reconfigure -phigh xserver-xorg

    I cant seem to disable my Nvidia onboard GPU, and my ATI card isn't being recognized, even though it works in low graphics mode. Did I use the wrong driver? Is there a way to set a primary video card?

    Thanks in advance!

    How do u know it recognises the nvidia card for sure.Be more specific.When you plug in the add on card it`ll recognise only that .Be more specific. try lspci command and see what it lists first.Also what i can infer from your xorg file is that u havent installed your driver properly .

    In display manager it says that my onboard nvidia was my primary display but i have a 3870 in the m/o. Also under restricted drive management it shows the integrated not the after market card.

    Can anyone refer me to an installation guide for my graphics card

    Advice is appreciated, thx

    Plug in the new card and try reinstalling the driver through restricted driver manager.It worked for me once when i was stuck at low resolution.

    That won't work because it doesn't recognize the card, just the onboard video card
