Ways to smooth touchpad/cursor coupling in Ubuntu 18.04

Problem Definition
When using the touchpad, the cursor sometimes jumps around a small amount and often fails to detect touch-click.
Attempted Solutions
Some searching suggested installing the old synaptics stuff, which had a dependency on xserver-xorg-core, which was not installed. Installing the package and all its concommitant dependencies yielded a GUI that not only didn't honor the touchpad, but didn't permit keyboard input. Reinstalled Linux from scratch.
Some History

It looks like Wayland is now the main vehicle, and some very good work has been done here. One of the commenters expresses concern about CPU usage, a concern I would take issue with given the critical nature of human-mouse pointer coupling (i.e. we're doing this for one process, not 1,000 processes; a little extra CPU for something critical isn't a big deal).

This gives me fine-tuned control for 3D model building and CAD work.
My Question to the Community
If anyone has been successful achieving smoother TouchPad operation with this hardware, I would be most interested to know how. My system is a solid older Dell which otherwise mates up very nicely with Ubuntu 18.04.
Thank you.
