Dual Display on Dell Latitude D600

Posted by ubuntufan on April 4, 2007

Most of you know that I have been using a Dell Latitude D600 at my new job. It’s not a bad little system. I do like the 1400×1050 resolution. Anyhoo, I needed to get dual displays working so I could drive an external 19″ LCD as well as use the real estate of the laptops LCD while I’m at my desk. I wrote a previous post on detecting dual displays and switching the xorg.conf but never got around to posting my actual xorg.conf file. Withour further delay, here it is:


# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# 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’m not doing anything fancy here. I do like the fact that I can have the displays running different resolutions and drag windows back and forth. This was a bit troublesome on my old T40. I think it was because I wasn’t using Xinerama but I can’t recall. I’ll have to try this out on my new T40…..pictures of the new laptop soon.

  1. Hi, I’m trying to configure my two monitors the same way you did, Two days ago I finally made them two work as extended monitors but the problem was that they were showing in the same resolution (1280×800) and I would like to change the resolution of my external monitor (not the laptop’s) to 1440×900. I’m playing now with the xorg.conf file, and I could achieve the resolution stuff, but now I can’t drag any window between monitors and the mouse pointer looks funny (a colored big square) on the external monitor.

    My xorg.conf file looks like this:
    Section “ServerLayout”
    Identifier “Default Layout”
    Screen “aticonfig-Screen[0]” 0 0
    Screen “aticonfig-Screen[1]” leftOf “aticonfig-Screen[0]”
    InputDevice “Generic Keyboard”
    InputDevice “Configured Mouse”
    InputDevice “stylus” “SendCoreEvents”
    InputDevice “cursor” “SendCoreEvents”
    InputDevice “eraser” “SendCoreEvents”
    InputDevice “Synaptics Touchpad”
    #Option “Clone” “off”
    EndSection

    Have any clue of what is happening? Ideally I would like to have both monitors working with different resolutions and be able to drag the windows…

    I appreciate if you can help me! Greetings
