Ubuntu – How to Ubuntu be made grayscale?


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?


Best Answer

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"

This might work depending on your video driver.
