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.

after being throught alot of problems dealing with Red Hat 9.0, because the screen was turning off everytime i started linux, so i made it boot into runlevel 3 so i can work on the shell to configure my monitor.
As i know i can configure the monitor by typing: Redhat-config-xfree86 on the shell screen after login as root.
The problem that when i type "Redhat-config-xfree86" on the shell screen the monitor turns off again, it seems there is a conflict between my monitor and the operating system.
how can i configure my monitor from the shell so i can enter the GUI ??
if anyone can help me i would be appreciated. thanx
You can manually edit XF86Config if you prefer, but it's probably simpler to just run the xf86config program, which, for each configuration option, typically gives a set of standard choices plus the ability to specify your own value. To use a real life example, you will need to specify the horizontal sync range and the vertical sync range for your particular monitor. You'll be given roughly half a dozen common values, plus an option to specify your own.
Overall it's a pretty simple program to run and as long as you correctly provide it with the appropriate values for your exact monitor model, it should give you good results. Obviously you can also achieve equally good results via manual editing, however, the potential for input errors or typos would be higher. -- J.W.
Originally posted by Pacemaker i know all the specification of my monitor, u mean i should pass the monitor specification to the XF86Config using the vi editor?
can some body explain me how to do this....PLEASE!!! i am really new in linux and i need redhat 9 right now...i think that i have the same problem, i know how to log as root....i already tried to run xfree86setup and xf86config and none of them worked....
i dont know how to use the vi editor...please somebody help me....give as many solutions as oyu can cause i gotta try everything till i see the penguin on my computer!
Well, as already described, the best way "to do this" would be to run the xf86config program, as that avoids the potential for manual editing errors, especially if you are not familiar with using vi. When you say that xf86config didn't work, what exactly do you mean? Did it give you an error message? If so, what was it? Perhaps if you describe your situation in more detail other people can make better suggestions.
As another alternative, if Redhat currently has not successfully been installed on your machine, then maybe the best thing for you to do is to just start over, and reinstall it. Towards the end of the process, you will have the option of specifying the make and model of your monitor. Redhat supports a pretty extensive list of monitors, and most likely the one you use is in there. Select the model you are using, and the vertical and horizontal sync rates will be correctly set automatically. If you are brand new to Linux and aren't having success with manual tweaks, then maybe doing a reinstall might be the fastest way to get the penguin up on your desktop. Good luck with the project -- J.W.
I am facing a similar problem (using fedora), although I am not sure how I can even log in as root, as the log in screen never shows up since the monitor sync rate is out of range. (Had to get a new monitor, not sure how to reset the rate without the old monitor...?)
Is there a way to get a command line prompt to show up using some keystrokes at some appropriate time during the boot? I see some of the messages that I used to see during the boot, about things being successfully turned on and such.
If I could get to a command line, at least I could try using the configuration tool, (is it XF86Config on Fedora as well?).
Distribution: Ubuntu Server, Slackware, Red Hat 6.1
You could try ctrl + alt + backspace. That shuts down the X server on my distro and just goes to the regular command prompt. I guess do the keystrokes right when your monitor begins to flicker and go black.
