Mike,

Thanks for the input.  I thought it might have something to do with that,
but my xorg.conf only references a single screen.  Here it is:

# Xorg configuration created by system-config-display

Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "Synaptics" "CorePointer"
EndSection

Section "InputDevice"
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105"
        Option      "XkbLayout" "us"
EndSection

Section "InputDevice"
        Identifier  "Synaptics"
        Driver      "synaptics"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "auto-dev"
        Option      "Emulate3Buttons" "yes"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "radeon"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1024x768" "800x600" "640x480"
        EndSubSection
EndSection


Is there anything you can see that I would need?  Understand that I
physically ripped the LCD off of the laptop, so it may not be registering as
a valid output.

Thanks,
Matt
