Yes we had someone on IRC a while back (like at least 5 years ago) who
was complaining of this, grayscale doesn't work anymore in xenocara, and
that may be the case in regular Xorg too. I guess we have zero users who
use this mode?

I'm interested in enabling a monocrome (greyscale) display mode,

Per some search results, I tried setting saturation with xrandr but
got an error:
$ xrandr --output DisplayPort-0 --set Saturation 0
X Error of failed request: BadName (named color or font does

Is there a straightforward way to do this globally?
Dmesg?
Depending on your graphics hardware, you might be able to run X11 in
8-bit static grey, or some other greyscale visual.
