I'm very new to KDE (running Kubuntu 18.10) and want to be able to quickly toggle grayscale through the terminal. I can make the script to do this but I don't know what to call to toggle the Desktop Effect.



Currently I'm using the extension described in this answer from this Github reop. Everything works great, the only problem is that I want to quickly switch to grayscale instead of going into System Settings > Desktop Behavior >Desktop Effects and click Apply. This is way to many steps for me to use more than once or twice a day.



My question is what command do I call to toggle this from the command line so I can write a script to do this?



I'm looking at the qdbus and trying something like:



qdbus org.kde.KWwin /Effects toggleEffect Grayscale


But nothing happens.
