I've installed the util from PPA
sudo add-apt-repository ppa:atareao/atareao sudo apt-get update sudo apt-get install touchpad-indicator
In the software preferences I've selected "Disable touchpad on typing" and "Disable touchpad when mouse plugged"
Both don't work.

I've remembered an important detail.
Sometimes ago (a week or two) I installed the same (I think) touchpad indicator on some other system. Unfortunately, I don't remember how I installed it, and what system exactly was, but I remember that it had a very useful option in its settings, something like "Input Source" or "Input Method". It was a dropdown menu with 3 options. By switching between options I was able to make Touchpad Indicator able to manage touchpad status. I want to have that settings again.
