frequency is out of range

[dick hoogendijk]

Lately I experienced a couple of times a *freeze* of my X session. The
computer does not respond on anything anymore. The OS has not died. I
can login (SSH) and force a shutdown -r now, but this is annoying.

What happens is that somehow my X (xorg-server-6.8.2_4) sneds a
frequency to my monitor which is out of range (monitor states: 105K /
234 Hz).

I wonder what can be the reason of thsi wrong freq. I have used DCC in
xorg.conf and also commented it out. It has happened in both occasions.
I also am pretty sure it ONLY happened when I was surfing the net with
mozilla (not sure of the relevance here).

I like to get rid of this issue asap. Or at leat want some info how to
deal with it. so, who can help me?

I have a NVidia GForce 6600GT which is driven by the nv driver. The
relevant portion from my xorg.conf:
