    Getting My External Monitor to work

    Ok, i'm pretty sure i've tried everything, and its really starting to bug me. I have a Dell XPS m170 with a broken display, so I have the laptop hooked up to an external monitor. I know the external can run a display of 1600x1200@70, and when I run displayconfig-gtk I get the external to run at 1600x1200, then it reverts right back to 800x600@60. I have an NVIDIA GeForce Go 7800 GTX, and the restricted drivers installed. I just don't know what else to do. Its really upsetting. Here is my xorg.conf file

    Code:
    # xorg.conf (X.Org X Window System server configuration file)
    #
    # This file was generated by failsafeDexconf, using
    # values from the debconf database and some overrides to use vesa mode.
    #
    # You should use dexconf or another such tool for creating a "real" xorg.conf
    # For example:
    #   sudo dpkg-reconfigure -phigh xserver-xorg

    Re: Getting My External Monitor to work

    Try xrandr which is a command line to displayconfig-gtk.

    This command tells you what is available:
    $ xrandr -q
    If you see that 1600x1200 is available you can set it up with this command:
    $ xrandr --output VGA0 --mode 1600x1200
    I am assuming that your external monitor is indicated as VGA0 in the output you get for the first command "xrandr -q" if it is slightly different change it.
