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.

Hi, i have just installed debian only to be greeted with a very high resolution... too high for my monitor. After installing the driver for my 9800 GTX the resolution changed to 640x480 and there were no other options to change it. I have read around the forums and changed my xorg.conf file to look like this:
# xorg.conf (X.Org X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
My monitor is a widescreen which is perfect at 1440x900 resolution but there is the problem. This xorg.conf , allthough stated resolution 1440x900 doesnt allow me to pick this setting neither in Nvidia settings or in Debian resolution settings. I can only choose 1280x800 even though there are other modes such as 1024x768. At 1280x800 my screen looks very blurry and lacks sharpness. I dont know what else i could do to fix this. Any help would be appreciated. Thanks in advance
At the risk of sounding like a nasty old grouch, I'll point out that the monitor displays the signal it gets from the graphics card. So, what have you done in re installing the nvidia driver (from nvidia, not the generic nv driver)?
I installed the driver from nvidia page. I couldnt change the settings in nvidia control panel so i edited the xorg.conf
What, exactly, does this mean? Does it mean that there was no option for 1440x900, or that you couldn't save it to xorg.conf after you had changed it? If the former, you're out of luck. If the latter, then open a terminal and run it this way: "gksu nvidia-settings". The problem is that you need root privileges to change xorg.conf and it generally runs as your userid, when selected from gnome.
The problem is that there was no option for 1440x900. I was stuck with 640x480 until i added the line to xorg.conf. Even though it sayd mod 1440x900 there is no option for that mod, only 1280x800 and 1024x768 which doesnt work.
That's strange -- I've never had this sort of problem with the Nvidia driver. What kind of monitor do you have (brand and model)? You should also tell us which version of Debian you are using and the exact error from your xorg log file when you try to start X with the xorg.conf you posted (look for lines beginning with (EE) in /var/log/Xorg.0.log). The first thing to do is make sure that the driver is loading correctly; the xorg log file will also tell you this.
I am using a HP w1907v widescreen monitor. When i load X with my xorg.conf it loads and i get no error but i dont get the screen is all blurry and not as sharp as it should be. There are several resolution choices but only 1280x800 and 640x480 work.
Here is the log from xorg.conf

it seems that the mode 1440x900 is not supported. I have tried to mess with xorg.conf and changed 1440x900 to 1280x800 and xorg.log says it is validated, however my screen resolution is still blurry and lacks sharpness. My monitor is optimized for 1440x900.
