I updated my system a few days ago, and noticed the touchpad gestures (managed by libinput-gestures) do not work anymore.
I am using a Logitech Rechargeable Touchpad T 650 (as xinput told me).
The command libinput-gestures -d doesn't list it (while it lists my laptop's touchpad).
Please tell me if you need more informations.
Have a nice day
