Title:
  laptop touchpad not working upon kernel upgrade

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  My laptop model: HP Spectre 13t-h200 x2 PC
  manufacturer of touchpad: I believe Synaptics. Supposed to have multi-touch (this works in Windows).
  Symptom appeared: every time I booted into the listed newer kernel version, as well as the ones after (or at least the newest one).

  When I was using kernel version 3.13.0-30-generic, the touchpad was
  able to move the mouse. It could not do a two-finger scroll and I
  would like to file this as a bug too, but I don't know where to file
  it (can you give advice?). However this is not the current issue.

  After upgrading to version 3.13.0-32-generic, the touchpad is no longer able to move the mouse. I have attached the `dmesg` output and the contents of '/proc/bus/input/devices' and /var/log/Xorg.0.log after booting into each kernel.
