How to Configure Screen Brightness in mate on pinebook via terinal?
I'm trying to bind brightness change to buttons via terminal in i3, but I can't find a command that will doing that:
pine64@pinebook:~$ sudo xrandr --listmonitors

Output is:

xrandr: Failed to get size of gamma for output default

Monitors: 1
 0: +*default 1366/361x768/203+0+0  default

So, when I trying to change it like:
pine64@pinebook:~$ sudo xrandr --output default --brightness 0.5

It isn't do anything. 

pine64@pinebook:~$ echo 240 > /sys/class/backlight/lcd0/brightness

Have not do anything too Sad
