    There are a couple of ways to do it. First, you can open kcontrol as root. Open a console and:
    Then select "peripherals" and "display" and you should be able to make changes there.

    The second thing you can do is reboot you computer with the Knoppix CD using the cheatcode: "knoppix screen=640x480" at the boot prompt. After Knoppix finishes booting into the desired resolution, you can transfer that configuration to your hard drive install:
    mount /dev/hdaX /mnt/hdaX
    cd /mnt/hdaX/etc/X11
    mv XF86Config-4 XF86Config-4.old
    cp /etc/X11/XF86Config-4 /mnt/hdaX/etc/X11/XF86Config-4
    Replace "hdaX" above with the number of the partition that you used for installation (like hda5).

    Finally, Morphix has a simple GUI X-configuration tool that has been ported to Debian from RedHat. You can download it here: It is called "xconf". Download the latest version as a *.deb file, then install it and use it:
    dpkg -i xconf*.deb
    It will open a window and you can make changes to screen resolution.
