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.

Could you provide full kernel logs?

Nouveau kernel git should be able to handle this now.
