autolight

Ruby daemon script for automatic monitor brightness adjustment on imac and macbooks under Linux.
Tested under Ubuntu 15.10 with Gnome 3.18

This script will work for you too if you have two files in you system

• /sys/devices/platform/applesmc.768/light (ambient light sensor current value source)
• /sys/class/backlight/acpi_video0/brightness (place to change for backlight brightness adjustment)

install

• Install Ruby if not
• (optional) Change config params in sctipt code

start

sudo ./autolight.rb

stop

sudo kill $(cat /tmp/autolight.pid)

I used the following code to create this script

  mba_autobl.rb https://gist.github.com/penguin2716/a0f48e4b3c14009c46ed

• @sbusso simple daemon gist
