Hi!
So, I have a rare neurological condition, and it is very important to me that I
can have control over color outputs from my monitor screen. After searching for
months, I have come to xrandr as the only available solution for linux to
change the behaviour of rgb channels. The problem is, it does not allow to
change directly the intensity of different rgb channels. It only allows to
change "gamma", whatever that is. When I set blue and green gamma all the way
down, grey colors turn into red. This is what I wanted. But the "gamma" option
does not make any difference for white. White is completely unaffected by
xrandr. Every other color get's filtered, except by white.
I am not sure whether this is a bug in xrandr gamma handling, or if the
technical definition of "gamma", which I cannot understand, implies that white
should in fact be unaffected. But it would be very important, then, to have an
option to directly control the intensities of output of each rgb channel. So,
if I wanted to shut down green and blue output entirely, I could.
Hope someone can help with this problem!
Thanks for your patience.
