Do AMD Linux drivers support native 30 bit color depth (10 bit per channel) over DisplayPort? What are software requirements to get 10 bit color opengl running? I'm talking about X server (Xorg) and driver configuration alone as I already have everything else configured and working properly with old Quadro card. I never used AMD cards before, do they have similar xorg.conf options where I can just set Depth to 30 or something?
Does AMD support 10 bit emulation by dithering on 8 bit panels?
