I know this is old and my answer is probably simple and obvious but under Settings/Mouse and Touchpad (I am using XFCE/Lubuntu), I had three devices simultaneously enabled: A Mouse, A dual-point Stick and a Touch Pad - As I am using a Dell Laptop with only a touchpad, disabling the other two devices and disabling the extra touch-pad features quieted everything down for me.
