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 just installed Mandrake 9.2, and this is my first experience with Linux. I got the OS installed, but I selected the wrong screen resolution during setup. I can't run X because the selected resolution is to large for the video memory. Is there a way I can change the resolution I want X to run in from the command line?
Check your monitor's manual or docs for the res and horiz and vert refresh rates it supports.
You will have to be root to edit the file, but you can view it as a regular user in your terminal using, oh, let's say, the 'cat' command. yeah.
use this command to look at your file first to see what you might need to change.
Once you are ready, change to the root user
su - root
then move to the dir
then save the current file in case you @#$% up bad.
cp XF86Config-4 XF86Config-4.old
use an editor to make and save the changes. then try to start X
Here is mine, note I am using the nvidia driver I downloaded and installed and i have a flat panel monitor that supports 1280x1024 res., and I have chopped out most of the sections you don't need to do something with to change the res. Don't delete any sections, just look for what to change. Where you see a line that starts with a # , that line is not in use as it is 'commented out' by the "#" symbol.
