Public bug reported:

Hello,

I have recently installed Kubuntu 20.04 (dual boot with Windows 10) and
the touchpad is not recognized. I typed: cat /proc/bus/input/devices but
it doesn't show nothing related to the touchpad. Besides, in "System
preferences" a message is shown "Touchpad not found". I checked in the
Driver Manager for updates but I can't found any drivers.

Thanks
