I'm not sure if the feature I want to activate is called Momentum. I want the cursor to continue moving in a direction like I'm pushing a ball. If I push the ball softy, it will continue moving a little bit after I lift my finger from the touch pad. If I push the ball harder, it will continue moving faster and further.
I have tried the command of the accepted answer of the following question, but that answer if for the scrolling Momentum and not for the cursor Momentum: How do I enable mouse momentum after release in kde/gnome/unity?
If we type: synclient | grep Momentum, we can't see any related command to activate the Momentum feature.
I'm on Ubuntu 14.04LTS.
