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.

       [menu.png]

       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.

ACPI_ASUS(4)						 BSD/i386 Kernel Interfaces Manual					      ACPI_ASUS(4)

NAME

     acpi_asus -- Asus Laptop Extras

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device acpi_asus

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   acpi_asus_load="YES"

DESCRIPTION

     The acpi_asus driver provides support for the extra ACPI-controlled gadgets, such as hotkeys and leds, found on recent Asus (and Medion) lap-
     tops.  It allows one to use the sysctl(8) interface to manipulate the brightness of the LCD panel and the display output state.  Hotkey
     events are passed to devd(8) for easy handling in userspace with the default configuration in /etc/devd/asus.conf.

     Currently, the following Asus laptops are fully supported:

	   xxN
	   A1x
	   A2x
	   A3N
	   A4D
	   A6VM
	   D1x
	   J1x
	   L2B
	   L2D
	   L2E
	   L3C
	   L3D
	   L3H
	   L4E
	   L4R
	   L5x
	   L8x
	   M1A
	   M2E
	   M6N
	   M6R
	   S1x
	   S2x
	   V6V
	   W5A
	   Eee PC

     Additionally, acpi_asus also supports the Asus-compatible ATK0100 interface found in Samsung P30/P35 laptops.

SYSCTL VARIABLES

     The following sysctls are currently implemented:

     hw.acpi.asus.lcd_brightness
	     Makes the LCD backlight brighter or dimmer (higher values are brighter).

     hw.acpi.asus.lcd_backlight
	     Turns the LCD backlight on or off.

     hw.acpi.asus.video_output
	     Sets the active display to use according to a bitwise OR of the following:

	     0	     No display
	     1	     LCD
	     2	     CRT
	     4	     TV-Out

	     Some models also support video switching via the generic acpi_video(4) driver.  Most models do not, however.

     Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.

HISTORY

     The acpi_asus driver first appeared in FreeBSD 5.3.

AUTHORS

     The acpi_asus driver and this manual page were written by Philip Paeps <philip@FreeBSD.org>.

     Inspiration came from the acpi4asus project started by Julien Lerouge which maintains a driver implementing this functionality in the Linux
     kernel.
