Re: how to turn off backlight in console (without any X server)

I did not install X on this machine since the screen is half broken. (i just use it as a server and acces it via ssh but screen consume power for nothing so i want somehow to turn it off).

I can install x and then try again xbacklight. This will be my next try...

Thanks again,

Laurent.

Hm Sorry. Are you able to change backlight under X? Perhaps there are clues
to be extracted from that?
