light 1.2.2 GNU/Linux application to control backlights

Light is a program to send commands to screen backlight controllers under GNU/Linux. Features include:

  • It does not rely on X.

  • Light can automatically figure out the best controller to use, making full use of underlying hardware.

  • It is possible to set a minimum brightness value, as some controllers set the screen to be pitch black at a value of 0 (or higher).
