My mistake, I tried again with the 'lubuntu-18.04.5-desktop-amd64.iso' file, and it did work.

What happens if you do a 'sudo modprobe i2c_hid' from within the live environment? Which iso did you try exactly, 18.04 or 18.04.5? Can you also check with the latest 'ubuntu-20.04.2.0-desktop-amd64.iso'?
So the working solution pulls in hid_multitouch when inserting i2c_hid, the non-working does not!

The log from Xorg.log when working is:
