Bug description:
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.
