Try this:

Section "ServerLayout"
       Identifier     "Default Layout"
       Screen      0  "Screen0"
      InputDevice    "Keyboard0" "CoreKeyboard"
      InputDevice    "Synaptics" "CorePointer"
EndSection



Section "Device"
          Identifier  "Videocard0"
          Driver      "nvidia"
          VendorName  "Videocard vendor"
          BoardName   "NVIDIA GeForce Go 6600"
          Option      "TwinView" "on"
          Option      "MetaModes" "CRT-0: 1024x768,  DFP-0: 1024x768"
          Option      "HorizSync"   "CRT-0: 50-100;  DFP-0: 31.5-90"
          Option      "VertRefresh" "CRT-0: 60-120;  DFP-0: 60"
          Option      "TwinViewOrientation" "Clone"
EndSection

IMPORTANT: in the above section CRT-0= video projector DFP-0= flat 
laptop panel CHANGE the "HorizSync" and "VertRefresh" values to fit yours

You will have a mean resolution of 1024x768 on both (flatpanel and 
projector)

Be careful that, with nvidia driver, as soon as you attach something to 
the VGA plug, it is considered as CRT and becomes the first display.

On some laptop, you have to toggle some Fn-Fx keys BEFORE the nvidia 
module is launched to get both display on panel and projector.

ALSO: make first a copy of your xorg.conf file.....
