@Coiby Xu (coiby) Apparently there was a similar problem with the 4.19 kernel, but with the Intel CPU, which was then solved with the following patch.
https://gitlab.manjaro.org/packages/core/linux419/-/blob/master/ELAN_touchpad_i2c_hid_pinctrl.patch Now the two lines are included (for example) in kernel 5.8 in /drivers/pincrtl/pincrtl-intel.c: /* Clear interrupt status first to avoid unexpected interrupt */ writel(BIT(gpp_offset), is); Maybe this information will help you. ** Attachment added: "pinctrl-intel.c" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887190/+attachment/5418857/+files/pinctrl-intel.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
