I have similar issue on my Lenovo ideapad Y700-17ISK; Ubuntu 20.04
I have since 2 or 3 times the correct touchpad recognised, but after a short time, it changes to PS/2 Generic Mouse, and I have no functionalities at all.
I have a different bug, reported, as I don't know if the issue it's the same or not...
