Description mickael.chazaux 2010-03-05 04:37:16 UTC 
By default, I get 6-bit color depth on my laptop. To get full 8-bit color depth on, I have to run the following command to manually enable dithering.
 
xrandr --output HDMI-1  --set dithering On

It would be great if Nouveau was able to turn on this parameter by itself when needed.

Nouveau kernel git should be able to handle this now.
