For those who want to try the polling mode i2c-hid, here are the instructions to build a single i2c-hid module without building a whole kernel or downloading the whole kernel source code,
1. After you download the attached file which contains patched i2c-hid-core.c and other headers for building, run make to build this module, $ make make -C /lib/modules/`uname -r`/build M=`pwd` make[1]: Entering directory '/usr/lib/modules/5.9.0-1-MANJARO/build' AR /home/coiby/Desktop/kernel/other/i2c-hid_standalone/built-in.a CC [M] /home/coiby/Desktop/kernel/other/i2c-hid_standalone/i2c-hid-core.o CC [M] /home/coiby/Desktop/kernel/other/i2c-hid_standalone/i2c-hid-dmi-quirks.o LD [M] /home/coiby/Desktop/kernel/other/i2c-hid_standalone/i2c-hid.o MODPOST /home/coiby/Desktop/kernel/other/i2c-hid_standalone/Module.symvers CC [M] /home/coiby/Desktop/kernel/other/i2c-hid_standalone/i2c-hid.mod.o LD [M] /home/coiby/Desktop/kernel/other/i2c-hid_standalone/i2c-hid.ko make[1]: Leaving directory '/usr/lib/modules/5.9.0-1-MANJARO/build' 2. Copy i2c-hid.ko to override the current one whose path can be found by modinfo $ modinfo i2c-hid.ko filename: /lib/modules/5.9.0-1-MANJARO/kernel/drivers/hid/i2c-hid/i2c-hid.ko.xz $ cp i2c-hid.ko /lib/modules/5.9.0-1-MANJARO/kernel/drivers/hid/i2c-hid /i2c-hid.ko.xz 3. run depmod $ sudo depmod 4. reboot the system and play with your touchpad ** Attachment added: "i2c-hid_standalone.zip" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887190/+attachment/5422428/+files/i2c-hid_standalone.zip -- 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
