Comment 16 for bug 385633

@Luís Silva :
Closing the lid should turn off the display completely. not just the backlight [at present it just turns off the backlight] ...

To check if your laptop is actually turning off the display and not just the backlight :
1: Play a video , [easiest to identify if the LCD is off]
2: try to *gently* press the lid switch. [be gentle, if you press too hard the pin *will* break]

now if the LCD turns off completely and you dont see any videos playing , your setup is working fine.

if you have trouble differentiating use > $ xset dpms force off
you will notice that there is no vide playing when you run the above command.

For me , i can see the videos playing when i use the lid switch. the lid switch only turns off the backlight. this was not how it was earlier.

And the burn-ins werent there earlier , its only after i had left a recent video file on the desktop in karmic , the thumbnail image got stuck!
similar happened to a window frame! the line of an open window got clearly marked!
[as i said, i keep this laptop running 24/7 ! which is a contributing factor]
