GoboLight

An ultra-simple backlight tool. Currently supports Linux.

Requirements

• Linux with a backlight driver that supports /sys/class/backlight.

Usage

GUI

There is a systray-style widget for Awesome WM: gobo-awesome-light

Command-line

The interface is via a simple command-line client, inspired by xbacklight:

• gobolight - Displays current brightness on a scale from 0 to 100
• gobolight <n> - Set brightness to n on a scale from 0 to 100. 0 means "display off"; 100 means "full brightness".
• gobolight -inc <n> - Increase brightness by n, capping at 100 (full brightness).
• gobolight -dec <n> - Decrease brightness by n, capping at 0 (display off).
