What video card do you have?
You'll need to determine the horizontal and vertical refresh rate ranges of your monitor, or determine which of the generic monitor settings will be adequate (choosing a generic may work fine, as long as the rates are correct, i.e. within the capability of your monitor).
To see the available settings, you can run the program: XConfigurator
In that utility you can select a generic monitor, and generic Geforce video card (generics work fine, it does NOT effect how well the driver works)
You may need to edit the config file, /etc/X11/XF86Config-4 to change one line in order to get the GUI working in basic 2d mode. You will need the nVidia drivers off their drivers download page in order to use 3d acceleration, basic openGL might work in software but is very slow.
Edit the file /etc/X11/XF86Config-4 with vi (or another text editor):
change the line:
and your GUI should work fine. If not, post the contents of that file on the forum, as well as the log file /var/log/XFree86.0.log. (copy them to a floppy or another harddrive partition if necessary)
