Which video card do you have?
If you have a radeon you need the so called "radeontool". 
And then just type radeontool for help and something like 
 "radeontool dac on"
  and/or radeon light off to shut the LCD.

Then you probably also need to configure xorg.conf in order to get the
correct resolutions on your CRT (if it is not a clone of the LCD).
I still like the CTRL_ALTFn+ or - to increase or decrease the resolution
of the LCD/CRT pair.

Here is the result of xrandr corresponding to my xorg.conf:
 $ xrandr
 SZ:    Pixels          Physical       Refresh
 0   1400 x 1050   ( 474mm x 356mm )   60
*1   1280 x 1024   ( 474mm x 356mm )  *60
 2   1280 x 960    ( 474mm x 356mm )   60
 3   1152 x 864    ( 474mm x 356mm )   60
 4   1024 x 768    ( 474mm x 356mm )   60
 5    800 x 600    ( 474mm x 356mm )   60
 6    640 x 480    ( 474mm x 356mm )   60
 7   1024 x 480    ( 474mm x 356mm )   60
 8    768 x 576    ( 474mm x 356mm )   60
 9    640 x 350    ( 474mm x 356mm )   60
 10   640 x 400    ( 474mm x 356mm )   60
 11   720 x 400    ( 474mm x 356mm )   60
 12   832 x 624    ( 474mm x 356mm )   60
 13  1152 x 768    ( 474mm x 356mm )   60
 14  1400 x 1050   ( 518mm x 365mm )   60
Current rotation - normal
Current reflection - none
Rotations possible - normal
Reflections possible - none

And for example my LCD is 0 (1400x1050) when I am undocked. But right
now the laptop is plugged to its dock station and my external CRT is of
lower resolution (1280x1024). (And I think that 1280x1024 is not
accepted by my LCD).

 - Then you need sonypid to have an event when Fn_F7 is pressed.

 - And you need a script (like sonyxosd) to attach this event to 
radeontool dac on && xrandr -s 4  (if you use a unique video projector,
but I prefer the CTL_ALT_Fn+ approach to xrandr).

But what I understand, is that your xorg.conf is probably not set with
enough possibilities. I give such a conf file on my site but some people
on this list are much more aware of what to do. Have a look at the
archives.

Cheers,

Nicolas
