Bug description:
  Expected: Touchpad settings available in Mouse & Touchpad Settings
  dialog

  Actual result: Touchpad settings missing entirely

  
  Details:
  The touchpad on my Dell Ultrabook (Latitude E7470) functions mostly. 

  The settings for the touchpad are not available at all in the Mouse
  and Touchpad settings (see http://i.imgur.com/YRGiOrj.png).

  Two-finger scrolling works as expected except it's using "Natural
  Scrolling" by default and there is no way to change it.

  xinput list does not display a touchpad at all:
