Securing Linux laptops
Mon, 07 Jan 2008 21:00:00 GMT
Laptop and notebooks are being stolen at an ever-increasing rate. In 2004, Safeware Insurance which sells computer insurance, estimated 600,000 laptop and notebooks a year were being stolen. In 2006 an estimated 750,000 were being swiped, according to Absolute Software a company that makes computer tracking products -- and does not support Linux. LoJack For Laptops, another computer tracing company -- which also does not support Linux -- says FBI statistics show 2 million laptop and notebook computers were stolen in the US in a recent year. While the figures may not agree in detail, they all show that laptop and notebook theft is a major problem -- and if you're not careful, your Linux laptop might be next.

armada-backlight

armada-backlight(1)						   User Commands					       armada-backlight(1)

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.
