modify xorg.conf for graphics card

I am installing kubuntu on a HP pavilion laptop.
I see some help here:

but I'm stuck at this part:

Change the driver which should now read "ati" or "radeon" to "fglrx". You'll also want to modify some other values, adding your resolution, 1440x900, which the fglrx driver will support.

Currently it is:

Section "Device"
Identifier "ATI Technologies, Inc. Radon Xpress 200M (RS480)"
Driver "ati"
BusID "PCI:1:5
EndSection

Can someone tell me how this should look?

Sure:

Code:

Section "Device"
    Identifier "ATI Technologies, Inc. Radon Xpress 200M (RS480)"
    Driver "fglrx"
    BusID "PCI:1:5
EndSection

Cool

You will also want to make sure your "HorizSync" and "VertRefresh" values are correct under Section "Monitor". These values should be in your laptops manual under specifications. If your horizontal and vertical refresh rates are correct it should give you the 1440x900 option. Should look something like this:

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 30-70
VertRefresh 50-160

I may be wrong but it has worked for me. A new install only gave me an option of 800x600 @ 60hz at best. After changing the vertical and horizontal refresh rates to my monitors specs I got all the options my monitor could support. Hope this helps.
