Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have an ATI Radeon 9000 Pro and I used the thread titled "ATI Radeon 9000 Pro Dual Display Problems" to get my dual display up and running:
Although, I'm having trouble setting up the exact dual display I want. Here is my situation:
I have 2 CRT monitors: One is an Envision 775e and the other is a Viewsonic E771. On my desk the Envision is placed on the left and the Viewsonic on the right. So naturally, I want the Envision monitor to be my "main" display and the Viewsonic to be the "extended desktop."
Right now I have the "main" display as the Viewsonic monitor and the "extended desktop" is the Envision monitor, which is placed RightOf the Viewsonic. Of course I could change that command to LeftOf but that still doesn't get me the "main" display where I want it.
Now, I know what you're thinking... just switch the monitor cables plugged into the video card, right? Well, that's where I run into my problems. When I do that, the displays revert to "Clone" and not "DualHead."
So does anybody know what I am doing wrong?
Any help is greatly appreciated!!
Below is a copy of my XF86Config file.
# XFree86 4 configuration created by C-Span
# The location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.
# Option "AutoRepeat" "500 5"
# when using XQUEUE, comment out the above line, and uncomment the
# following line
# Option "Protocol" "Xqueue"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:nocaps"
# Option "XkbOptions" ""
Option "XkbRules" "xfree86"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
#Option "XkbVariant" ""
