    [Solved] How to extended display on dual monitor on Xubuntu 12.04 LTS

    Hello There,
    I Recently installed Xubuntu 12.04 LTS on my Dell Precision 1650 desktop( it has Nvidia Card).
    It Ubuntu certified desktop. I have added another monitor to this deksotp on DVI port.
    But i dont see any option to extend display i have attached the screenshot of "Settings->Display", all i can do is set the resolution for both.

    Earlier when i had added second monitor on VGA port , it dint work. After i pluggin into DVI port its detecting it but I am getting the identical display on both, while i want to extend my display.



    Another point ( if its important) I have connected the second monitor using a DVI splitter cable, I am not sure if that makes any difference.

    Proper multi-monitor support isn't available in the version of Xfce that comes with 12.04, so you'll have to use arandr. Look for it in the software centre or, from a terminal window:
    Code:
    sudo apt-get install arandr
    Once installed, you'll find it in the Settings Manager. Double-click to start it up. Drag the monitors to position them how you would like them then Layout->Apply.

    To make it permanent (so you don't have to run arandr everytime you login):
    1. Layout -> Save As (select a name, default save directory is ~/.screenlayout)
    2. Create a startup entry (Settings Manager -> Session and Startup -> Application Autostart) where the command will be:
    Code:
    /home/<USER>/.screenlayout/<FILE>
    ...where <USER> is your username and <FILE> is the filename you gave in the previous step.

    Using PPA, in the Xfce Settings Manager. select the position of each monitor you want to mirror the displays or not.
    The PPA currently provides Thunar 1.5.x, Xfce4 Settings and Axo development builds. To add the PPA and upgrade these packages in Xubuntu 12.10 or 12.04, use the commands
    sudo add-apt-repository ppaubuntu-dev/xfce-4.12
    sudo apt-get update
    sudo apt-get upgrade

    Once the packages have been successfully upgraded, open the Settings Manager, and under "Display", uncheck the "Mirror displays" option to extend your display to the external monitor.

    However the display quality is not great with this tool.

    If by "display quality" you mean the resolution is less than ideal, you can set a different resolution for each display by right-clicking the display's box in arandr and selecting a different resolution.
