A20 - shut the LCD ?

[otyugh]

Hey,
any idea how I could make the LCD screen "shut" in stead of having a "shiny black screen" ?

Thanks for any tip ! (and generally if you know tips to reduce energy consumption while under battery ; lowering CPU, lowering luminosity, using hdparm or such, I really care to hear about your practice !)

Shiny black means that the backlight is still active.

Which OS are you using. I run Android and it properly powers off the LCD and the backlight.

I almost forgot ! It's debian.

Even If I'd be more intersted by a way to manage de backlight intensity.
