Doubtful that any of this should really be neeeded as most reasonably modern lcd screens should give all the required info to X via EDID.

Take a look at the log file /var/log/Xorg.0.log and see if edid data is being received.

A better description of the hardware and the actual problem may lead to further help.

Google will know those numbers.
What's the make and model of your lappie?

/etc/X11/xorg.conf is the ultimate screen definition file if that's any help.

Get the screen properties from the manufacturers website, and look for the 
following sections:

Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       28-96
        VertRefresh     43-60
EndSection

Section "Screen"
        Identifier "Screen 0"
        Device     "Graphics Adapter 0"
        Monitor    "Generic Monitor"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
                Modes    "1400x1024" "1280x1024" "1024x768" "800x600"
        EndSubSection
EndSection

You'll be wanting to change the HorizSync, VertRefresh and Modes in the above 
section to support your lappie.

hth,

I've had issues with my screen resolution with the screen not filling
the entire screen of my laptop. I went to System - Preferences - Screen
Resolution the refresh rate drop box has only one setting 0 hz which I'm
assuming is causing my problem.

I remember there's a text file to alter these settings but can't
remember where it is. Any pointers?
