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.

Is there a way to enter my RedHat 7.2 system in text mode? I have to change monitor settings because the new one can't handle the refresh rates of my old setting. I don't have my rescue disk nor my RedHat 7.2 cds with me.
I assume that your system starts you in an X session (KDE, GNOME etc..) and you want to exit this session? If this is correct all you have to do is type [CTRL]+[ALT]+backspace to exit your x session, then (AS ROOT) edit the /etc/inittab and change the line that reads:
This will make it so you start in text mode upon restart.
You can run the "setup'" command (as root) to reconfigure X.
Try ctrl-alt-f1...f6 and see if you can get a console window. If you do, log in as root and run the command ' init 3 '. That will take you out of runlevel 5 and you can redo your X settings. When you want to try out your new settings, just run ' init 5 '. I hope this helps.
