Title:
Touchpad not working (4.3 -> 4.4 regression)
Status in linux package in Ubuntu:
Incomplete
Bug description:
When booting the latest xenial kernel (4.4.0-2.16), my touchpad is not
working. When booting 4.3 kernels, the touchpad is works.
Expected: When I move a finger touching the touchpad, an arrow should move
accordingly on the screen.
What happens instead: nothing.
I've tried an upstream 4.4 kernel; problem is present there as well.
I've booted with pci=noaer due to another bug that would otherwise
spam dmesg. Removing it does not fix the problem.
