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. Note that for distributions like Ubuntu and Fedora, the pinctrl-amd
driver is built into the initramfs. So you have to rebuild the initramfs after
replacing the old module with new one.
On Fedora, run `sudo dracut --force`; On ubuntu, run `sudo update-initramfs
-u`.
The complete solution is three patches,
- 47a0001436352c9853d72bf2071e85b316d688a2 ("pinctrl: amd: remove debounce
filter setting in IRQ type setting")
- 06abe8291bc31839950f7d0362d9979edc88a666 ("pinctrl: amd: fix incorrect way
to disable debounce filter")
- 8dcb7a15a585b6d0fee15751ce11d7a68cfedd56 ("gpiolib: acpi: Take into
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.

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)

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.

[Desktop-packages] [Bug 1887190] Re: MSFT Touchpad not working on Lenovo Legion-5 15ARH05
Lenovo R7000P Laptop. Sadly, still not a good solution. The touch pad
now works with kernel 5.11.0, but it has problem with Nvidia GPU and the
brightness control is not working. I can have Nvidia GPU working and
manually do some fixes to enable brightness control with 5.8.0, though
touch pad is not working.
