How to Configure Screen Brightness in mate on pinebook via terinal?

[MarkHaysHarris777]

Excellent dude!  


I got my bindings to work too, in i3,  with bindsym(s) in  ~/.config/i3/config

... but first I created a group called gpio_pins,  to give permissions to write to the file brightness, and added my pine64 user to the group!

 Also, I added a rule to my sudoers configuration ( use visudo ) similar to this:

# my extra rules
Cmnd_Alias LCDBRIGHT=/usr/local/sbin/lcd_bright.sh
ALL ALL=NOPASSWD: LCDBRIGHT

Then in ~/.config/i3/config  I added a bindsym near the bottom:

bindsym $mod+Shift+u  exec  sudo lcd_bright.sh u 10
bindsym $mod+Shift+d  exec  sudo lcd_bright.sh d 10

Then,  restart i3  with mod+Shift+r

...  now  mod+Shift+u  turns up the brightness,  and  mod+Shift+d  turns down the brightness.

nice
