I've been having this problem for a while now, and it happens at strange times. First, the individuals involved here:

Fedora Core 3
NEC MultiSync LCD1765 17" display
NVidia GeForce2 MX

I have the 'nvidia' drivers installed already, not the 'nv' drivers.
My problem is that the display becomes extremely jittery and jumpy at times when the system is working in the background. When it is sitting idly, the display is smooth and sharp. It is absolutely killing my eyes. I've searched around for this problem for a while, and because of that, I have edited my /etc/X11/xorg.conf file around a bit.
I got the numbers for the horizontal sync and vertical refresh from NEC's website, though I could be wrong on the actual numbers here...

Here's what I have in my xorg.conf monitor section...

Here is the URL for specification info on my monitor, am I making any mistakes with the horizontal sync and vertical refresh between 31.5-81.1 and 56.0-75.0 respectively?

Also, when I make changes to this file, do I need to reboot to see if the changes have been made?

Thanks a TON in advance..
