Public bug reported:
After upgrading to `linux-image-4.15.0-72-generic`, both the touchpad
and trackpad stopped working completely.
The devices still show up in `xinput list` as well as libinput list-
devices`. However, using `libinput debug-events --device
/dev/input/event...` I get
`-event14 DEVICE_ADDED Synaptics TM3288-011 seat0
default group1 cap:pg size 97x53mm tap(dl off) left scroll-nat scroll-
2fg-edge click-buttonareas-clickfinger dwt-on`
but touching the pad or pushing buttons does not generate any events.
Switching back to `linux-image-4.15.0-70-generic`, everything works
again as expected.
