How to disable dithering on NV Qaudro FX
X.Org server 1.6.5
SLED 11 SP 1 ker. 18.104.22.168
very bad performance out of "PCoIP - KVM extension" when using NV Qaudro FX 380/580 cards. The cards are OK when connected directly without PCoIP part.
The problem seems to be related to dithering - frequent unnecessary screen updates.
How can I permanently disable dithering?
How to check the state of dithering?
I have tried following with no success:
GPU-0 - DFP-0 - Dithering Controls - Dithering Auto (switch to disabled)
it keeps on being auto - How to save disabled option?
configuration of xorg.conf
Option "Dac8Bit" "False"
Option "RegistryDwords" "DitherAlgo8=3; DitherAlgo6=3"
It does not work for me.

Re: How to disable dithering on NV Qaudro FX
The nvidia-settings control panel in recent 270 releases also has an option to disable this (in the settings panel for each display).
[edit: sorry; the 260 control panel has this too, as noted by johncom, but the setting isn't persistent unless added to the X config.]
