Title:
  Dell Inspiron 15 7000 series (7537) laptop's touchpad unusable because
  during window moves or drag and drop items move around wildly

Status in xserver-xorg-input-synaptics package in Ubuntu:
  Confirmed

Bug description:
  Touchpad for the Dell Inspiron 7537 cannot move objects on desktop
  without troubles. I have tried this under the GNOME, KDE, and Unity
  desktops and they all show the problem so it is not there. I have the
  latest (A10) BIOS from Dell and am running a fully up-to-date Ubuntu
  14.04.

  It is the intergrated touchpad (well, clickpad since there are no
  distinct buttons) for one of Dell's most popular laptops. A web search
  finds other people having similar trouble.

  You cannot move windows around because they jump around wildly making
  the device practically unusable. It requires using an external mouse
  with the laptop.

  Problem is almost surely with the Synaptic driver for the touchpad.

  Here's the output of "lspci" if that helps:
