Setting a greyscale (or monochrome) color scheme

Question

I would like to see everything on my computer screen in grayscale (like say the kindle screen). How do I do this?

is this also available in ubuntu 14.04? I don't have the color filter option in Accessibility nor anywhere else :/ anyone? — , Oct 10 '14 at 19:04

Compiz has a few filters which supposedly can do what you want.

Install Compiz Config Setting Manager from Ubuntu Software Center or with sudo apt install compizconfig-settings-manager.
Run it and under Accessibility category you'll find Color Filter and Opacity, Brightness and Saturation filters.
There you'll be able to enable them, assign a keyboard shortcut and edit the filters' settings.

Now, I have to admit that I wasn't able to test it since I only have Ubuntu in a virtual box without 3D acceleration, but hopfully it'll give you some pointers.

Also, please don't get too excited modifying Compiz settings - it is quite easy to break Unity by doing so. The filters I mentioned above should be quite safe though.

I can confirm that the monochrome color filter works nicely. – Chris H Dec 05 '13 at 13:35
I know this is an old answer, but what if when I install it and I only have but a few of the options? I only see "general" in the lefthand menu. – Kard Nails Mar 24 '20 at 08:52
@KardNails You are more likely to get a reply by asking this as a new question. – Daniel Werner Mar 27 '20 at 14:02

As soon as I personally visited this answer at first in 2022, I would recommend to see this answer, where GNOME bedtime extension is a solution.
Works good for me as it has its own settings and not dangerous (seems like that) at all to crash your system.
