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 got some problems with the resolutions....... i use RH9 and i installed a new graphic card some geforce4 mx se 128mb and then ....... when i try to go to the x it just gives me 800x600 and that sux!!!!
well i tried to put it to another one like 1024x768 and nothing i restard X and it gives me 800x600 :S weird!!!! i modify the XF86Config manually and put it there "1024x768" and when i try to go to gdm it gimmes a error and i cant see the X windows so????
Do you have a Windows dual boot? If so, run your monitor at the desired resolution in Windows, press the menu button on the front of your monitor, and check the Vertical Refresh and Horizontal Sync Rates. For example my monitor runs at 1280x1024 and the Vertical Rate is 75.3Hz, the Horizontal Refresh is 80.3kHz. As you can see, both my figures are outside the range defined in your XF86Config file. In fact your XF86Config file is restricting your monitor to ridiculously low refresh rates. This is what happens when your monitor is not listed and you pick a generic one.
I had a problem with picture instability, so I increased my upper figures on the HorizSync and VertRefresh lines to 81 and 76 respectively and now Linux uses the same rates as Windows and all is well.
If you don't have Windows do you know the claimed figures for your monitor. For example if your monitor is capable of 75Hz, your XF86Config file is restricting it to 70 max, which in effect is 60Hz. Worse, if like my monitor, the Horizontal rate for 60Hz is 64kHz, then your XF86Config file has ruled this out altogether so the system will not be able to run the monitor for you.
It has nothing to do with installing the nVidia drivers: all they do is enable 3D OpenGL mode and improve 2D a bit, but they will not override this setting.
If you do not have a Windows dual boot, you will have to increase the upper limits. However I suspect that with Generic monitors, the defaults are low for a good reason: you don't want your monitor fried! Perhaps you can get the data from the manufacturer. If not, perhaps you can increase the rate in small steps until something works, keeping your fingers crossed as you go!
well about the dual boot yeah i am using XP too and i installed some refreshtool to make it up to 100.
i got in the windows 1024x768 Hz 100 sorry but i got the windows xp in spanish and when i do right click to the desktop and go to monitor it say "frecuency of refresh or something like that!!! " is 100 Hercios and maybe ... that is problem.
The refresh rate that he is referring to is given by your monitor, not windows. Windows is just the other operating system that you'll go into so your monitor is using the frequency you desire. Then you take that and edit your XF86Config file to show that frequency.
Sorry Tusnal what I meant was you go into Windows and switch to your favourite resolution. Then you press the button ON YOUR MONITOR and you normally get an on-screen menu, and have to select from a number of options. The one that works for me is a logo with a letter "i" in the middle. When I select that on mine I get a reading which says 80.3kHz 75.3Hz. The one which says Hz is your Vertical refresh rate and the one which says kHz is your Horizontal sync.
