This problem persists with Ubuntu 20.10 released today.
The modprobe/rmmod/modprobe method above still works there, however it
is very inconvenient to have to perform those steps after each reboot.
Unfortunate, as Ubuntu has been the distro that I've used and
recommended to others for the last
FWIW, I do this dance after boot and the touchpad works...
➜ ~ sudo modprobe psmouse
[sudo] passord for ole:
➜ ~ sudo rmmod psmouse
➜ ~ sudo modprobe psmouse
Sincerely,
Ole

The problem persists on 5.4.0-48 sadly, I still need to select advanced in
grub, selecting 5.4.0-42 for the touchpad to work.
*➜ ~ xinput --list*
*5.4.0-42*
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer
Kernel 5.4.0-48 fixes the problem. The TouchPad is recognized correctly
and touch pad, buttons, and track point work. Thank you.
