Is there a kernel option I can put on the grub kernel boot line to make the default setting for the Broadcast RGB option be "Full"? Ever since the default changed, I've had this annoying "mist" over my screen :-). I would like to set the option at boot time if possible so the boot messages are clear enough to read. I can set it after boot with the xrandr command, but I'd love to blow away the mist earlier than that.
Lacking that, does anyone have an actual working example of a file I could stick in /etc/X11/xorg.conf.d to set this option on the HDMI2 output? The xorg docs all seem to be encrypted text that only looks a little like english...
