I had the same issue when using Fedora and find out it's caused by the
pinctrl-amd driver being stored into the initramfs. Maybe the same thing
happened to ubuntu. You can try re-building the initramfs by running
`sudo update-initramfs -u' after replacing the old module with the new
one.


** Description changed:

- Update (#296)
+ Update (based on #296)
  =============
  
  The latest kernel tree
  (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git) has
  the complete solution to fix this bug. So we can expect kernel v5.11 to
- fix this issue without any additional work. Before the release of v5.11,
- you are suggested to use #189 to save your touchpad.

filter setting in IRQ type setting")

to disable debounce filter")

account debounce settings")

  The first two patches has reached the stable tree. If the last one is
  also backported to LTS kernel, you won't need to install kernel 5.11.
  But I don't know when this will happen.

  Original bug report
  ===================
  
  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.
