Comment 5 for bug 1919042

Hello,
please refer to the "How do I install an upstream kernel?" section in https://wiki.ubuntu.com/Kernel/MainlineBuilds

After booting with the mainline kernel (you can check the kernel version with `uname -a` command) please check the touchpad function again.

Testing mainline kernel will allow us know if your hardware works in the Linux world.

If your touchpad is still not working with the latest mainline kernel, it means that your hardware is not supported at all. You will have to report this issue to https://bugzilla.kernel.org/
