I have exactly the same issue.

Touchapd Synaptics TM2869-008 working perfectly fine with kernel 4.15.0-70 under Ubuntu 18.04 LTS.
As soon as I updated kernel to 4.15.0-72, touchpad stopped working.

Booting back to previous kernel, touchpad is working perfectly fine.

I had the exact same problem, and downgrading back to version 4.15.0-70 worked fine for me, but upgrading to 5.4.2-050402 worked for me as well.

I have this same issue on Ubuntu 16.04. Booting into an older kernel fixes the issue for me. This is on a Dell XPS 13.
