Grayscale display settings

[max.nichts...@posteo.de]

Hey there,

what is the best way to switch my whole display to black and white /
grayscale?

I found this thread:
https://askubuntu.com/questions/443335/how-can-ubuntu-be-made-grayscale/443346#443346

But I'm unsure where to implement this in dom0.

Thanks!

Max

Those settings would go in /etc/X11/xorg.conf normally, I seem to remember.
Qubes doesn't have this file in a default setup, but you could try adding one.

You need to search for X11 configuration settings.
