dear guys,
I have a problem between my CentOS 5.5 (on Axioo notebook) and LCD 
Projector. When I connect my notebook to LCD Projector, it can detect my 
notebook.
But when I press Fn + F7 to activate dual monitor between my notebook 
and LCD Projector it goes to blank screen. FYI, the LCD Projector is NEC 
but I don't know the series.
I've tried to change display using dual head monitor but it has no 
effects. Do I need some driver??

and this is my xorg configuration :
Section "Device"
        Identifier  "Videocard0"
        Driver      "openchrome"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes    "1280x800" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection

Hope you guys can help me. Thanks.

My experience is this is due to the internal screen having a resolution 
that the external projector cannot handle.
Solution:
change your internal LCD screen resolution to one that the projector 
understands.
