JM,

Thanks for your response.

Yeah, the laptop screen doesn't appear to want to work with X (virtual
terminals work fine).  It won't even work if the 24 inch isn't plugged
in.

Thanks I created the following minimal xorg.conf:

Section "Monitor"
        Identifier      "Builtin Default Monitor"
EndSection
Section "Device"
        Identifier      "Intel"
        Driver  "i810"
EndSection
Section "Monitor"
        Identifier      "Generic Monitor"
EndSection

Section "Screen"
       Identifier      "Default Screen"
       Device          "Intel"
       Monitor         "Generic Monitor"
       SubSection "Display"
               Depth           24
               Virtual         3320 1200
       EndSubSection
EndSection

When I run:
$ xrandr --output LVDS --auto --left-of VGA

It no longer complains, the virtual desktop size appears to increase
(everything shifts left), but the laptop stays blank.

Attaching the log from using the new xorg.conf.
