X710 LCD

I'm using this screen with M3 on debian. How can I change screen brightness (backlight) or how can I switch the screen completely (not blank it - as I see, the backlight is still on)?
Using /sys/ filesystem or any other programmatical method.


You need to use this command to change screen brightness:
#echo 0 > /dev/backlight-1wire

the number '0' means the darkest, the number you can use is 0 to 127.

thank you!
