I have Fedora-4 installed on a Virtual PC, and I'm trying to figure out how to change the screen resolution.

How do I access the menu for changing the screen resolution?

    Open KDE Control Center ,  and from the left-hand pane click on + (plus) before Peripherals to expand the list of periferals configuration tools. Select Display and from there go to Monitor (tab) and change the resolution.
    Note that you'll get full list of supported screen resolutions ONLY if you've selected correct video card driver and monitor model.
    You can also try   system-config-display    command line tool   but it's somewhat scale-down vresion of
    Cotrol Center config tool which has more config options.
    good luck

    I just found the option to change the resolution, which was under Desktop->Preferences->Screen Resolution

    However, I only had 800x600 as the max.

    I'm sure this is because I don't have the right video card selected.

    Does anyone know what is the right video card to select for Virtual PC 2004 or Virtual Server 2005?

    And how to change the video card selected?

    Hi Axter

    what chipset it is?

    Would make thinks more easier if you run :

    'lspci' from command line to see what VGA you have.

    >>'lspci' from command line to see what VGA you have.
    I get the following:

    VGA compatible controller: S3 Inc. 86c764/765 [Trio32/64/64V+]

    now check your:

    /etc/X11/xorg.conf (if you have one, if not XF86Config-4 ) file

    and correct the settings to your S3 driver. It may happen that you have correct driver but in Section "Screen"  of this file you have only 800x600 which explain why you have only this option available.

    hope this helps

    have you tried changing the horizontal and vertical frequency ...

    1) cp /etc/X11/xorg.conf  xorg.old
    2) vi xorg.conf  
    and change the vertical and horizontal frequencies ....make the horizontal a bit higher than the vertical

    3) if anything goes wrong , you can restore the file
        cp xorg.old  xorg.conf

    thats it
