  1. Cannot get video res above 800x600

    Having mucho trouble bumping the screen res above 800x600 on several
    Linux machines
    (FC2, FC4, FC6).

    I have modified /etc/X11/xorg.conf as follows with no success:
    SubSection "Display"
    Viewport 0 0
    Depth 24
    Modes "1280x1024" "1280x960" "1152x864" "1024x768"
    "800x600" "640x480"
    EndSubSection

    I have also tried commenting out the 'Monitor' values "HorizSync" &
    "VertRefresh". No dice.

    I have spent far too much time on something that should be so simple.
    This is BS.
    Thoughts?

    Thanks,
    -Richard Vaughn

    How are you trying to change resolution? Are you using the gnome or kde
    configure option? If not whatever they say will over-ride whatever you do to the
    file.

    Have you checked the string: DefaultDepth ?

    I've had that problem too. I find that if I set my monitor up as a
    generic svga type (even though the monitor is supposed to be supported) I
    can get higher resolutions.

    What is the video card? I had that problem with the display on my gateway
    laptop. Evidently the video bios on the intel graphics adapter is borked.
    ONLY solution I could find was the commercial driver from xigraphics. They
    have a free trial download to see if it will work for you.

    I've had a similar problem, eventually (after more than a year )
    adding a modeline to xorg.conf fixed it:

    Section "Monitor"
    Identifier "Compaq 1024"
    UseModes
    EndSection

    Section "Modes"
    Identifier "960x720"
    Modeline "960x720" 66.36 960 1008 1112 1264 720 721 724 750
    -HSync +VSync
    EndSection

    The values I copied from the nvidia control panel in windows.
    I don't know what they should be for your monitor/card combination, but
    if you google for "linux modeline calculator" you'll find some tools
    that might help you out.

    You have not told us what the trouble is. Or what your wireless card is, or
    anything. or what your other entries in xorg.conf are....

    This looks suspiciously like you have a carriage return at the end of that
    previous line. There should not be.

    Now why would you comment them out? Make sure that they are correct, rather
    than commenting them out.
