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.

Kernel driver in use: nouveau
with the nouveau driver running.
This is supposed to be the new standard in Debian squeeze with the nouveau driver replacing the old nv driver.
The problem is that with the nouveau driver installed .mpg .wmv .avi
and other similar files will not play with mplayer, vlc or aviplay. All
I see is either a pure green screen or a mostly green screen with parts
of the image in bars. The audio is fine. The flashplayer still works.
To disable the nouveau driver I have to turn off the kernel mode setting. I did this by creating a file I called 'nouveau-kms.conf'
with the single line:
options nouveau modeset=0
and installed the file in the /etc/modprobe.d folder. I next created an /etc/X11/xorg.conf file:
:~$ more /etc/X11/xorg.conf
# xorg.conf (X.Org X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
[I added the "Option "HWCursor" "off"" line because I encountered
a problem with my mouse cursor disappearing both in nouveau and the
After adding these files and running:
sudo update-initramfs -u
I was able to reboot with the nv video driver installed which works just fine. With this setting I can also run the nvidia driver from
nvidia: NVIDIA-Linux-x86_64-256.53 with a corresponding xorg.conf file.
The only problem is that with any kernel or xorg update I have to re-install the nvidia driver.
I guess my problem is a fix for the nouveau driver. I've filed a bug
report to Debian with no feedback. Looking through bug reports I can't
seem to find instances of this being reported & wonder if it something unique to my system.
