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.

To correct a misperception: Yes, I HAVE been reading every thread I can find in here on solutions to refresh rate problems. Many solutions differ from one another, and I take it that some of this has to do with the distro, and with the version of X. For me, a mere newbie, it is bewildering beyond belief - the sheer number of different solutions.
Yes, I DID utilize the Colas modelines utility, but all or any part of it's output (from lines values like "1152", to the dot-clock value) entered correctly in monitor section of XF86 Config-4, and X will not reboot.
My distro (BearOps) rep. said they abandoned modelines (insert/adjust) capability in this latest release (2.4.18-ac2-rc2) - I don't know why. They are Linux experts, and they can't get this distro to refresh above 85Hz. I have exhausted my help time with them. I am just a raw newbie, so I cannot be expected to outperform Linux experts in this refresh rate area.
One of you got to 110Hz. I'd be incredibly grateful if any of you could help me get my setup to refresh at 100Hz (as I use in Win). I noticed
some desktop modes/refresh utilities out there, but so far, none will unpack on my machine.
Thanks all! (maybe I should just wait for Linux 2.5? or 3.0?). Linux is fantastic too, just to clarify that part! -Tunes.
Try to do xf86config and give it 100-120 Hz when it asks for the monitorfreq. It shouldn't be possible then to get a lower freq than the lowest number - as far as I understand it.
Just give it a shot - all you got to lose is a monitor and a card!
Just a monitor, if it doesnt have the auto-shutoff feature on frequency overclock specs (which can be annoying but it saved my butt since im very daring hehe)
There is no way you can damage your video card, unless you overclock that too which there is zero point in doing if you just want a better refresh rate. Most video cards today are WAAY ahead of the monitors they run on, this is one area the hardware industry needs to advance in IMO.
Btw, if you feel daring you can try the program in /usr/X11R6/bin/xvidtune its old, and came out around the time 14" monitors were normal but it works in adjusting the h and v. personally after playing around with it for 30 minutes i gave up as it would always mess up my monitor. Be aware, this isn't like PowerStrip in windows where it automatically calculates the correct Htotal and Vtotal values for the given frequency, good luck. Oh and one more thing, dont hit the Apply button unless you know its works well, also if you DO hit apply (daredevils) hit R to restore the previous setting that was working.
One more thing, just so you know i figured out why my monitor doesnt want to overclock in linux:
the xvidtune program does NOT raise the Pixel Clock when you alter the scan rates, therefore edges of the screen my kinda 'fad' away from view, this is becuase the higher Hz you run the higher pixel clock it needs for the beams of light to scan the entire screen.
My monitor only runs @ at 130Mhz pixel clock by default, i need to get a new one :P
