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 installed PCLinux OS in my HP Pavillion Laptop. I tried Ubuntu and openSuSe before, but only this distribution made everything run out-of-the-box including the webcam, wireless, multimedia buttons. Even the current version of of proprietary Nvidia driver worked for the laptops GeForce Go 7200 graphics.
Apparently, PCLinuxOS Full Monty does not support compiz because it is incompatible with some of its setup. So I followed a work-around and was able to install compiz:
1) Executed the command:
/usr/bin/su -c 'rm -f /etc/apt/preferences'
2) In synaptic, reloaded repos, and then installed compiz,compiz-fusion and task-3ddesktop
3) Created a new user account.
4) Enabled 3d by login in to the new account
5) Rebooted the laptop.
But to my disappointment, I encountered a black screen with only the mouse pointer after the reboot. To get a working graphical screen, I disabled 3d effects by creating two files in the home directory
Now, I have a working desktop, but without 3d effects.
Please help me in configuring compiz as I use XBMC which requires 3d. Am I missing any steps?

Edit: never-mind the above two commands unless you are trying to force compiz to start. But what you do need to do is to update your video drivers, and if you have more than one GPU, make sure to update both to the most recent version; check the manufacture web sites.
This code is used to force compiz to start. It is not used to get rid of the black screen. The black screen is a video problem. Also one way to get rid of the black screen is to stop compiz from starting. That's what I had do do to stop my white screen with mouse arrow from happening until I could get the video driver issue resolved, then when I tried to get compiz to start again I could not until I found the above code and used it.
