I'd like to make everything grayscale. The utility xcalib can be used to invert the colours displayed (every colour displayed is changed to its compliment) using the following command:

xcalib -i -a

How could I make the display grayscale? Could I desaturate in some way, for example?

Thanks!

See How do I make my display grayscale in Ubuntu with GNOME desktop? and How to make the screen grayscale in Ubuntu flavors (non-GNOME)? for Ubuntu 18.04+

You could also add the following to your xorg configuration to achieve a greyscale output:

Section "Screen"
    Identifier "greyscale configuration"
    Defaultdepth 8
    SubSection "Display"
        Depth 8
        Visual "GrayScale"
    EndSubSection
EndSection

This might work depending on your video driver.
