blackened screen 2

[Tom Horsley]

This certainly doesn't make my screen too dark to see, but it
does make me think something is wrong with my eyes: Apparently
the Intel video driver now defaults to some nonsensical color
range restriction. I have to run this in a startup script:

xrandr --output HDMI2 --set "Broadcast RGB" Full

I feel like someone removes the gauze from the front of the
screen when I do that :-).
