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 recently purchased a new video card and monitor for my machine (running Fedora Core 3).
Unfortunately, I cannot generate or tweek my xorg.conf successfully enough to use X. The default configuration displays an image on the screen which is displaced horizontally such that left and right boarders are at the center of the screen (a wide dark area), and the middle of the image is off the monitor. The vertical placement seems fine.
I did some homework and a fair amount of research, but I've come up empty. According to the Video-Tuning howto, if the image is displaced horizontally, the center two values of the HTimings parameter should be shifted (by multiples of 8). I've taken the modeline values from the X startup log and worked from there, but so far have been unsuccessful. The displacement doesn't seem to change at all, or the monitor gives me "sync out of range" errors.
The video card is an AGP Mad Dog Champion MX400 (NVidia) and the monitor is a Memorex MM1940 19" flat panel. I['ve also tried using the read-edid utility the XFree86-Video-Timings refers to and I get errors reading the values.
I can post the xorg.conf, lspci output and the X startup log, but thought I'd throw this out there first and see if anyone has any advice on what to try next. Any help would be greatly appreciated as I am one frustrated person right now!
boot into init level 3 and run Xorgcfg or X --configure
Since you should have the manual for the monitor, enter the Horizontal and Vertical Sync frequencies and the video card information when it asks.
I tried that before. The same problem occurred. I just loaded windows on an old box a few minutes ago and tried the monitor on that (just wanted to see if the problem was unique to X) and sure enough, the same problem is there. Perhaps it's a defective monitor. I'll call memorex for support and see what they say.
