Forget everything up to now - it is a kernel bug that has been known since January of this year and for which there has been a fix since then. I can't say why it hasn't been included in the kernel so far.
Here is the patch: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux- next.git/commit/?id=d25e8fdebdad84219b498873300b7f11dd915b88 It's been included in Manjaro Linux kernel >= 5.8.13-4 (5.9 with the next update) https://gitlab.manjaro.org/packages/core/linux58/-/blob/master/0305 -gpio-amd-fch.patch The bug was, that at /drivers/gpio/gpio-amd-fch.c the line "return ret ? GPIO_LINE_DIRECTION_IN : GPIO_LINE_DIRECTION_OUT;" was wrong. It must be correct "return ret ? GPIO_LINE_DIRECTION_OUT : GPIO_LINE_DIRECTION_IN;" A small swap that unfortunately has a big impact on the owners of a Lenovo Legion. -- 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
