Public bug reported:

Started Ubuntu 20.04.2 LTS installation right after receiving my new 'Lenovo 
Ideapad 5 14ALC05'.
Everything worked fine during installation.
However, after the installations restart, touchpad doesn't work at all.
Keyboard and other peripherals like wireless mouse work fine.
Running 'cat /proc/bus/input/devices' and 'xinput' it seems that the touchpad 
isn't recognized.
