how to change refresh rate ?

[Rivendell]

Hi everyone

I have a monitor nec FE700+, it can do 85hz at 1024x768. and a knoppix clone called Damn Small Linux.
Can anyone tell me which file or files are responsible for refresh rate.
my system use 60 hz. I tried to use xf86config, and edit /etc/X11/XF86Config, but it doesn't work. are there any other files in which screen refresh rate can be changed

note: there is no Xf86Config-4
I'm looking forward to any suggestions from you.
Thanking you in anticipation Rivendell

Could you post your original XF86Config file? What are the specifications for your monitor? Vertical and Horizontal refresh rates? You should be able to get that either from the manual or at the manufacturers website.

This is a part of my XF86Config I removed from it font and keyboard section.
I think that this problem is caused by autoconfiguration program which doesn't recognize my video card ( Nvidia Riva 12. I installed drivers but i don't exactly know where in XF86Config write which driver to use.

Usually it would be something like this:

# Standard Server
Section "Screen"
Driver "nv"
Device "My Video Card"
Monitor "Monitor0"
Subsection "Display"
Modes "1024x768" "800x600" "640x480"

What is it exactly that's wrong w/ your resolution?
