[Metagoudabuntu]

Can someone tell me if this:
(RGB LIMITED):
sudo intel_reg_write 0x70008 0x40002000
sudo intel_reg_write 0x70008 0xC0002000

is effectively the same as:
DISPLAY=:0 xrandr --output HDMI1 --set "Broadcast RGB" "Full"

Is one persistent while the other is required to be run at startup?

Anyway I have a haswell i3 nuc and have run both of those commands in a terminal in the same Ubuntu session, and I like the black level, don't see obvious crushing.

What is the easiest way to run the remote/black script from this thread on Ubuntu at startup? I like to boot to xmbc manually.

FWIW My issues so far have been similar to others but I think most are work-aroundable (for _my_ videos at least on a panasonic S50).
Needed to Boot-Repair because of UEFI not installed by the live disk.
Sound not playing initially (just clicked on something green in settings)
Gray instead of black (scripts above).
Some video tearing out of the box.
