[Cin] 10bit display links

[Andrea paz]

I don't think it depends on CinGG. Even Steam has problems with 10-bit
(crashes!). Other programs (Firefox) show no difference between 8 and
10-bit, and others work fine at 10-bit (mpv). No differences both X11
and X11-OpenGL. I think the basis is always the lack of color
management of various programs.
To create a new X server: sorry; you ask too much of my rusty little
brain! Anyway it's a matter of renaming the 20-amd.conf file to
20-amd.conf.back and rebooting, it's not very long.
