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.

If I tried using a range it seemed to keep going to 50Hz and there wouldnt be any other options in the drop down list to select from.
That's what would happen if your xorg.conf hasn't got the DisableTwinView line; it's a bug in the nvidia driver (or is it? nvisia blames Gnome). Once it was inserted, I could choose from the full set of ranges again.
can only assume that the buzzing sound is the screen, before you ask I am almost certain its not a fan or the HD or something like that.
I don't know, I've never had to deal with anything like that. I don't think a screen would make any sound, it's more likely the GPU or CPU that is getting stressed under certain conditions.
The Modules section you mentioned...should I just copy yours or specific lines from it?
You can copy all ot them. Just make sure that you have a back-up and that you they are copied properly.
As for the refresh rates, have your been able to verify that those are the exact rates supported by your monitor? I find it weird that your vertical rates are somewhat higher than the horizontal ones. This is unusual considering that
- horizontal rates of LCDs as a rule are higher than their vertical rates
- vertical rates of CRTs as a rule are MUCH higher than their horizontal rates
Note that too modest rates will result in lower overall refresh rates. Note also that setting them higher than what is supported will result in a blank screen! Always try to find documentation first.
Output from the log file does point to something interesting...
(WW) NVIDIA: No matching Device section for instance (BusID PCI:0:10:3) found
(WW) NVIDIA(0): No valid modes for "1152x864"; removing.
(WW) <default pointer>: No Device specified, looking for one...
I can't find out what screen I have...its a laptop so im presuming its LCD. I really know very little about screens. I just can't find any real techincal details for the laptop -- its an HP Pavillion dv6000.
I hope the warning messages above provide some sort of clue.
Exactly. Try using 0:10:0 instead - or simply put a hash in front of that line so that it gets skipped (the system will figure out where the card is; and also, not defining any BusID is always better than defining it incorrectly).
As I said, the refreshing seems a bit better -- I am getting less horizontally distorted lines. Furthermore, one of the warnings I got from my Xorg.log has gone...the one that said a certain resolution wasn't available. That resolution is now available when I go to System -- Preferences -- Screen Resolution.
However, I still can't choose from a list of refresh rates
Oh and those stupid comments have stopped being automatically generated !
That's great. As for the fixed rate, I still suspect this is related to the horizontal and vertical refresh rates. It happens to me as well when I set either (or both) incorrectly. Unfortunately, it seems impossible to find more details for your screen. You can start by gradually lowering the vertical rates since that is the least risky experiment. Raising the horizontal ones may work but it may just as well produce a blank screen. Make sure to have a back-up.
