Title:
[Lenovo IdeaPad S145-15IIL] Touchpad doesn't work

Status in linux package in Ubuntu:
Incomplete

Bug description:
I'm using a computer Lenovo IdeaPad s145 and I've installed Ubuntu 20.04 LTS and my touchpad doesn't work at all. xinput gives:
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech Optical USB Mouse id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Integrated Camera: Integrated C id=9 [slave keyboard (3)]
↳ Ideapad extra buttons id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=11 [slave keyboard (3)]

Moreover, if I execute cat /proc/bus/input/devices it gives me only
the mouse device and not the touchpad. What can I do?

Thank you for your help
