Turning off screen in Linux

[Linux for blind general discussion]

Schoepp here...

Why not setting the brightness of the screen to zero via the normal Mate 
settings? In the settings for power management it is possible to reduce 
the brightness of the screen so it is totaly dark. That saves energy and 
also lets sighted persons not see the content of the screen..., which is 
annoying for some of my colleagues regulary ;-).

Ciao,
