Hello

The MSFT touchpad of this Lenovo Legion-5 15ARH05 laptop is not reacting at all (pointer and click never move when touchpad is touched). This has been reported by other users in various websites, with various linux systems including other Ubuntu systems, but I saw no launchpad bug so I post one. Example of websites covering the issue :
- https://askubuntu.com/questions/1253830/lenovo-legion-5-touchpad (exactly the same laptop)
- https://www.linux.org/threads/lenovo-legion-5-touchpad.29536/ (similar laptop)

xinput indentifies it as MSFT0001:00 04F3:3140

Thanks a lot for your time. It does not help, but I can confirm what was reported on askubuntu by another user : the touchpad does work on Windows.
