Thank you everyone for fixing this, I've been following this thread for
the last few weeks and today is the first time I've managed to get it
working.
For any noobs like me that are on Ubuntu this is the guide that I
followed to upgrade to kernel 5.11 and everything works perfectly for
me, both the touchpad and the brightness controls.
Upgrade kernel
Change current directory to /tmp
cd /tmp
Download the latest mainline kernel from 5.11.x branch by copying
and pasting this:
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-headers-5.11.0-051100rc2_5.11.0-051100rc2.202101032030_all.deb
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-headers-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-image-unsigned-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
wget -c
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.11-rc2/amd64/linux-modules-5.11.0-051100rc2-generic_5.11.0-051100rc2.202101032030_amd64.deb
Install new kernel
sudo dpkg -i *.deb
Reboot the system
sudo shutdown -r now
Update packages list
sudo apt-get update
Upgrade packages
sudo apt-get upgrade
Reboot the system if needed
sudo shutdown -r now
Check the OS distro
lsb_release -a
Check kernel version
uname -r
That's it, now you should be running on the Linux Kernel 5.11rc2

Thanks to everyone for their hard work, sorry for posting this noob
guide here but it took me weeks to figure out an easy way to do it
(patching was beyond my abilities).

Bug description:
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. 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.
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)

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.
