Add the following lines to your Device Section to force X to treat your flat
panel as the primary output.

Option         "UseDisplayDevice" "DFP,CRT"
Option         "TwinViewXineramaInfoOrder" "DFP-0"


Under the Screen Section, I have these (my CRT is left of the DFP):

    Option         "TwinView" "1"
    Option         "TwinViewOrientation" "LeftOf"

Also, I have these in my Screen Section, but you may need to tweak for your
specific configuration:
    Option         "metamodes" "CRT: 1280x1024 +0+0, DFP: 1680x1050 +1280+0;
CRT: 800x600+0+0, DFP: nvidia-auto-select +800+0; CRT: 640x480 +0+0, DFP:
nvidia-auto-select +640+0"
    SubSection     "Display"
        Depth       24
        Modes      "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
    EndSubSection

Good luck.
