User will need to add i8042.noloop=1 to boot options to make it work. [Fix] * a48491c65b513e ("Input: i8042 - add ByteSpeed touchpad to noloop table") This fix can be cherry-picked into all affected releases. [Test Case] Test kernel for Bionic / Focal can be found here: https://people.canonical.com/~phlin/kernel/lp-1906128-C15B/ And they have been tested with positive test results. [Where problems could occur] The fix is just a small and simple hardware quirk. I can't think of any potential problem for now. == Original Bug Report == Touchpad hardware is OK and works for Win10. Not working for live disc, not for 18.04 and not for 20.04 after upgrading. I've attached a Logitech wireless mouse with its USB adapter and that works. Bluetooth is also missing, but I have not started trying to skull that out. I'm happy to help try debugging things, and to help resolve the issue.
