Touchpad not working at all

[Darrell Bacarro]

I have a Lenovo Thinkpad L480 Laptop. It is dual-booted with Windows 10 and Ubuntu 19.04. When I boot to Windows, the touchpad works with no problem, but on Ubuntu, the touchpad doesn't work at all. I have attached the devices list generated from the Terminal. Hope you can help. Thanks.

Note: Using USB Mouse works.
