  1. Instead of ***-icons just use ‘sudo apt-get install indicator-keylock indicator-keylock’, that worked for me.

  2. Brilliant. It works a treat. But is it possible that in settings one could change the colours used for on and off, and in my current theme there is not really as much difference as I’d like. But anyway, thanks for the app.
