Hi all, 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.
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. Thanks to all who have participated in the process of bug hunting, especially to @wangjun (biggerchina), @Mike Boruta (maridius), @Helmut Stult (helmut-stult) and @Baq Domalaq (baq). I spent about one month of my internship at the Linux Foundation on this bug. So I should also thanks to the Linux Foundation for funding this work. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-libinput in Ubuntu. https://bugs.launchpad.net/bugs/1887190 Title: MSFT Touchpad not working on Lenovo Legion-5 15ARH05 To manage notifications about this bug go to: https://bugs.launchpad.net/pop-os/+bug/1887190/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
