Keyboard backlight

Hi everyone,
I have this in my i3 config:

bindsym XF86KbdBrightnessUp exec --no-startup-id light -s sysfs/leds/smc::kbd_backlight -A 5
bindsym XF86KbdBrightnessDown exec --no-startup-id light -s sysfs/leds/smc::kbd_backlight -U 5

but light works only if I'm root, so I can't use this as a regular user..
What is the right way to make it work?

Re: Keyboard backlight

Use an appropriate entry in your sudoers file so you can run sudo light without a password.

Re: Keyboard backlight

You could also check the permissions of the backlight file and either add your user to a relevant group or alter the permissions of the file (with a udev rule) to grant your user (or any group) access.
