I'm running 19.04, with everything updated. The touchpad feels rather jittery as it moves across the screen using libinput, as if its resolution isn't great; this makes the rest of the system feel sluggish as well. It's a lot more smooth under Windows 19, as well as Ubuntu using Synaptics. A random mouse is far smoother. Is there a way to improve the resolution?
