This thread only deals with the touchpad issue and it's too long to follow. But I've summarized what's needed in the beginning of the bug report. As far as I know, the fix for the touchpad doesn't affect nvidia issue. In fact, I don't experience any of the issues you mentioned including external monitor not detected and brightness issue on Manjara with kernel=5.11.6-1 after installing optimus manager [1]. [1] is "a port to Archlinux of the nvidia-prime solution created by Canonical for Ubuntu" so I assume the issues of external monitor and brightness don't bother Ubuntu users either.

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) xinput indentifies it as MSFT0001:00 04F3:3140 Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ MSFT0001:00 04F3:3140 Touchpad id=17 [slave pointer (2)] ⎜ ↳ MSFT0001:00 04F3:3140 Mouse id=16 [slave pointer (2)] ⎜ ↳ ITE Tech.
