Using external monitor, lid closure disable should disable laptop screen.

This is not really a serious problem, but I would really like it if when I'm 
using my external monitor and I close the lid of the laptop, if the internal 
LCD screen would automatically disable so I wouldn't need to worry about 
windows or my cursor moving to the closed screen. It works that way in W7.  

What version of the product are you using? On what operating system?
I'm using VPCF11JFX with Kernel 2.6.35 on ubuntu 10.10

Please provide any additional information below.
I tried changing the power settings to have the laptop screen go blank upon lid 
closure, but it still counts as an active screen. It seems much of the display 
detection is not very robust, as unplugging the HDMI cable does not 
automatically disable the external monitor registering as an active screen 
either. 

I'm a pretty big linux noob, so there's probably something really dumb I'm not 
doing... Sorry....
