Title:
  [Acer Travelmate B115-M] Synaptic touchpad not correctly detected in
  kernel 3.16 after upgrade to Ubuntu 14.10

Status in linux package in Ubuntu:

Bug description:
  Since the upgrade from Ubuntu 14.04 to 14.10 the Synaptic touchpad is
  not detected entirely. The secondary key (right mouse button) does not
  work with kernel 3.16.0-23-generic. Falling back under Ubuntu 14.10 to
