Public bug reported:
After updating (16.04), multi-touch features of my touchpad such as two-
finger scroll and the ability to turn off touch to tap were broken. I
have tried using libinput and synaptics drivers but the touchpad is
recognized as an ImPS/2 Synatpics Touchpad, and drivers determined by
"pointer catchall" rather than "touchpad". I upgraded to 17.04 to see if
the new kernel 4.10 helped, but I have the same problem.

keyboard and touchpad on my laptop work, the high frequency of jumping
around and clicking of the touchpad make it very frustrating to work
with the laptop without external devices.
