This may be related to bug #1903858 “Synaptics Touchpad not working dynabook TECRA A40-G”.
Release: Kubuntu 20.10 freshly out of the box. (The same problem observed with live versions of Ubuntu 20.04.)
xserver-xorg-input-libinput:
Installed: 0.30.0-1
Candidate: 0.30.0-1
Version table:
*** 0.30.0-1 500
500 http://gb.archive.ubuntu.com/ubuntu groovy/main amd64 Packages
100 /var/lib/dpkg/status
Problem:
Touchpad _almost_ does not work at all. The cursor moves a little from time to time, and reacts to buttons from time to time, in an indeterminate manner. There is no problem under Windows – touchpad works perfectly well there.
Not sure this problem is specific to libinput. Tried replacing it with synaptics (as described here: https://askubuntu.com/questions/1088559/ubuntu-18-04-switch-back-to-synaptics-as-input-driver) and the problem persisted.
Attaching various files suggested by https://wiki.ubuntu.com/DebuggingTouchpadDetection.
