Hi Cara, and Davide,
I was talking to another member of the kernel team, and he mentioned he
was working on an issue that seemed very similar to the issue you both
have hit.
After looking into it more deeply, we are sure that they are the same
issue.
He has made more progress on the issue, and has reproduced it. I will
be marking this ticket as a duplicate of
https://bugs.launchpad.net/bugs/2080355 and @vpeixoto will continue the
investigation.

Title:
Lenovo Touchpad not working or detected in 'Lenovo Legion 9 16IRX9'
following Ubuntu 22.04 installation.
Status in linux package in Ubuntu:
Confirmed
Bug description:
The Lenovo Legion 9 touchpad on my laptop is unresponsive after
installing Ubuntu 22.04. How might I get it working again? A lot of
solutions suggested to downgrade the kernel but the posts I found were
from 2+ years ago.
Below is the output from 'cat /proc/bus/input/devices'. Note that the
Logitech mouse is a (functional) wired mouse I was using at the time.
