HI,
if the gui tools are not working, you can also edit the config file. The 
lasteast releases of X has the config file name changed (it's in Fedora 2 and 
RHEL 3 is probably the same). I think it is now called /etc/X11/xorg.conf or 
something, the older one is /etc/X11/XF86Config. Make a backup copy, then 
edit it and add multiple resolutions to the display section (example below) 
then restart X and you will be able to cycle thru the resolutions with "ctrl 
alt +" (contol, alt and the num pad's + or - key). Not sure how well that 
works on a laptop.

Here is the section you want to look for:
Section "Screen"
        Identifier "Display 1"
        Device     "MATROX CARD 1"
        Monitor    "Display 1"
        DefaultDepth     24
        SubSection "Display"
                Depth     16
                Modes    "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth     24
                Modes    "1280x1024" "1024x768" "800x600"
        EndSubSection
        SubSection "Display"
                Depth     8
                Modes    "1280x1024" "1024x768" "800x600"
        EndSubSection
EndSection


Above, X will try to start with the default colour depth (24) at 1280x1024. 
So if your shows 
  Modes    "800x600"
try
  Modes    "800x600" "1024x768"

Hope that helps.
