    The Xorg.conf file is blank.

    apparently Karmic doesnt have a Xorg.conf file with settings by default but will use it if you create one (or for example if NVIDIA propietary driver install creates it) so do this...

    Code:
    press ctrl+alt+F1
    to start in a console. log in with your user name and password. then do this:
    Code:
    sudo service gdm stop
    to stop the gdm service. then this:
    Code:
    sudo Xorg -configure
    to create a new xorg.conf with your settings. onces this is created, karmic will use it.then to go back to your normal session:
    Code:
    sudo service gdm start
    after this you will have your xorg.conf file in the usual directory. then if you need to add settings to it you can and Karmic will use those settings.

    hope this helps. let us know.

    Thank youtreleyan that was very helpful!

    The problem persists. I cant get System/preferences/Display to show a 1024x768 resolution.

    Thank you.

    Re: Low Resolution with Ubuntu 9.10

    I installed 9.10 on a friend's PC who wants to switch from windows. All is great, except I am having the exact same problem as Sebastian. The highest resolution is 800x600. My screen (vizio P50 HD20A) has a native res of 1366x768, but 1024x768 would also work great.

    I have followed all the instructions given on this thread just as Sebastian, with the same results as he posted. I would be glad to help if I can as I obviously have the same problem. Also, I tried the tip on stopping the gdm and the 'Xorg -configure' command, but still don't have a Xorg.conf file.
    ...Through the Fire and the flames we carry on.
