Comment 15 for bug 1854798

The following link contains a test kernel that can be used to confirm the fix for this issue:

https://kernel.ubuntu.com/~kmously/kernel-kmously-2019795-5QnR/

This kernel is the 4.15.0-72-generic kernel plus one change: Revert 'Input: synaptics-rmi4 - avoid processing unknown IRQs'

For anyone testing this kernel, a minimum of 2 files need to be installed:

linux-image-unsigned-4.15.0-72-generic_4.15.0-72.81~k1_amd64.deb
linux-modules-4.15.0-72-generic_4.15.0-72.81~k1_amd64.deb
