Title:
  'Synaptics Clickpad' / "HP Imagepad" incorrectly detected as PS/2
  mouse in 'HP Stream 14'

Status in “linux” package in Ubuntu:
  New

Bug description:
  The clickpad acts like a standard mouse. Single-tap to click works, two-finger-scroll, two-finger-tap etc. don't work. The device is not configurable via the synclient tool.
  The 'Touchpad' tab in System -> Preferences -> Mouse is missing.

  The clickpad should be recognized as a Synaptics touchpad and the
  associated module should be loaded instead of the evdev one.
