    Dual Monitor & Dual Graphics card help

    I have installed Kubuntu Gutsy Gibbon on a desktop that has two Samsung SyncMaster 940bw connected to two separate nVidia G80 GeForce 8600 GT (PCI:1:0:0 and PCI:4:0:0) I am trying to set up so both monitors work. The installation process automatically set up one monitor up, but I cannot seem to figure out how to set up the second. Any help would be greatly appreciated. Below are my xorg.conf and startx responses:

    Re: Dual Monitor & Dual Graphics card help

    If you installed the nVidia drivers using the restricted drivers manager, you may be able resolve your issue using nVidia's control panel.

    type this code into console

    Code:
    sudo nvidia-settings
    Here you should be able to set up each screen that is connected, then append changes to your xorg.conf.

    I hope this helps

        Thank the guys at nVidia, they put together something that resembles what you'd see on a MS windows based system and somehow managed to get it to work on this Linux distro.
