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 acquired a ViewSonic VP2330wb monitor. Unfortunately, I have been unable to get linux configured to use the full width of the monitor (up to 1920x1200). I have tried several different resolutions (1920x1200, 1440x900, 1280x800), several different configurations of the /etc/X11/xorg.conf file where I set the resolution by hand in the file, choosing different configurations of the "Monitor Type" in the "System Setting"->"Display"->"Hardware" menu. It appears that I can't get linux configured for this aspect ratio. In the "System Setting"->"Display"->"Setting" none of the resolutions listed have the correct aspect ratio. The video card is an Intel Corporation 82915G/910GL Express Chipset Family Graphics Controller. I'm using the Intel 915 driver. This is all running on RedHat Linux Enterprise 4 on an IBM Think Center MT-M 8104. I'm basically out of ideas for how to get this to work. Any help would be greatly appreciated.
P.S. I'm new to this group so I apologize ahead of time if I miss something obvious.
Could you give us a bit more info please? What distro are you using? Can you post the relevant portion of your xorg.conf file? I'm guessing the problem is in your xorg.conf file, particularly with the horizontal or vertical refresh rates.
Thanks for the replies to my post. I have tried all the recommended changes to my xorg.conf, but none have worked. In fact when I put in the latest suggestions for the horizontal and vertical sync rates, the monitor just gave me an 'Out of Range' message and sat there. I was able to cntrl-alt-delete to halt the X-server and recover, but it appears that my video card just can't handle these resolutions. I'm surprised, since this is a new machine, but our IS people have a history of less-than-astute choices. I have started looking into new video boards. If anyone has any recommendations, please let me know. I am currently considering an nVidia GeForce 6800 GT/LE. The driver for it is listed under the 'Configure' menu for the video card for linux and the nVidia website claims it can do all resolutions up to 1920x1200. Thanks again for all your help.
I'm currently using a GeForce 6800GT in my main system and I'm pretty happy with it. I'm not sure if it will handle the widescreen ratio you're looking. I run it at 1280x1024 and I know it will go quite a bit higher. I'm just not sure about that specific widescreen format.
