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? – user336384 Oct 10 '14 at 19:04

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

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

Compiz Config Setting Manager

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 5 '13 at 13:35
