# mackbook-lighter

MacBook keyboard and screen backlight adjust on the ambient light.

Internally, macbook-lighter reads the following files:

* /sys/devices/platform/applesmc.768/light

* /sys/class/backlight/intel_backlight/brightness

* /sys/class/backlight/intel_backlight/max_brightness

* /sys/class/leds/smc::kbd_backlight/brightness

* /sys/class/leds/smc::kbd_backlight/max_brightness

So you're expected to install corresponding Nvidia/Intel drivers first.

## Setup

All commands including macbook-lighter-kbd, macbook-lighter-screen

will be available with sudo previledge once macbook-lighter finished install.

To use in non-root environment such as [xbindkeys](https://wiki.archlinux.org/index.php/Xbindkeys),

it's recommended to setup an "udev" rule to allow users in the

"video" group to set the backlights.

Place a file /etc/udev/rules.d/90-backlight.rules containing:

```

SUBSYSTEM=="backlight", ACTION=="add", \

  RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness", \

  RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"

```

And a file /etc/udev/rules.d/91-leds.rules containing:

```

SUBSYSTEM=="leds", ACTION=="add", \

  RUN+="/bin/chgrp video /sys/class/leds/%k/brightness", \

  RUN+="/bin/chmod g+w /sys/class/leds/%k/brightness"

```

## Usage

```bash

# Increase keyboard backlight by 50

macbook-lighter-kbd --inc 50

# Increase screen backlight by 50

macbook-lighter-screen --inc 50

# Set screen backlight to max

macbook-lighter-screen --max

# start auto adjust daemon

systemctl start macbook-lighter

# start auto adjust interactively, root previlege needed

macbook-lighter-ambient

```
