    Problem with Nvidia quadro NVS 450 and Linux Enterprise


    Only 3 out of 4 screens recognized when using Nvidia quadro NVS 450 card with Linux Enterprise 4.6. Output on port 1,2 and 4?

    I use latest Nvidia device driver.

    I have tested 2 different cards, with same result.

    It recognize 2 screens on PCI:4:0:0 but only 1 screen on PCI:3:0:0

    Any suggestions?

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Post the contents of your /etc/X11/xorg.conf file here please.

    Well, I won't say that I'm an expert with xorg.conf setups, but I have some experience. To my eye, and at first glance, yours looks ok to me. However, in the videocard sections there appear to be some anomolies in definition.
    Code:
    Section "Device"
    Identifier "Videocard0"
    Driver "nvidia"
    VendorName "Videocard vendor"
    BoardName "Quadro NVS 450"
    BusID "PCI:4:0:0"
    EndSection
    
    Section "Device"
    Identifier "Videocard1"
    Driver "nvidia"
    VendorName "Nvidia Corporation"
    BoardName "Quadro NVS 450"
    BusID "PCI:4:0:0"
    Screen 1
    EndSection
    
    Section "Device"
    
    # Screen 0
    Identifier "Videocard2"
    Driver "nvidia"
    VendorName "nvidia"
    BoardName "Quadro NVS 450"
    BusID "PCI:3:0:0"
    EndSection
    
    Section "Device"
    Identifier "Videocard3"
    Driver "nvidia"
    VendorName "nvidia"
    BoardName "Quadro NVS 450"
    BusID "PCI:3:0:0"
    Screen 1
    EndSection
    I don't know if these are the cause of your problems or not. It's the only thing I noticed, however.
