NAME

       armada-backlight - Adjust Compaq Armada backlight

SYNOPSIS

         armada-backlight [-h|--help] [[+-]value]

DESCRIPTION

       Values:

          None   Prints the current brightness level to stdout.
          +      Increases the brightness of the backlight.
          -      Decreases the brightness of the backlight.
          value  Sets the brightness of the backlight. Value must be between 0 and
                 8, inclusive.

       The Armada Backlight Controller is a program for controlling the brightness of the LCD
       backlight on Compaq Armada[1] laptops under Linux. It has been tested on an Armada M700
       running. It is based on code by George Acher[2], which was written for the M300 and has
       been used on the E500. This package should also work on those machines, although that has
       not been tested by Nat Pryce, who put the modified package together.

       The program is divided into two parts:

        1. A command-line program that is installed with privileges that
           allow it to control the backlight hardware (aka an "suid" program).

        2. A GNOME panel applet that provides a convenient GUI to the
           command-line program.

       An alternative way of using the command-line program is to configure your X window manager
       to run it in response to key sequences such as Alt-F10 to make the screen brighter and
       Alt-Shift-F10 to make the screen dimmer (in Compaq Armada, the F10 key has a brightness
       icon on it).

       GNOME Panel Applet

       The Armada Backlight Controller applet is installed into the Utility category of the GNOME
       Applets menu.

       When added to the panel, the applet presents a scrollbar that can be used to interactively
       control the brightness of the backlight and also shows the current level numerically. The
       icon identifies the applet in the panel and can be used to access the applet menu using
       the right mouse button.
