It really seems a linux driver bug, since it happens also with Fedora 21
running on the same hardware with the exactly the same behavior: if you
reboot system, the touchpad pointer behaves as it should.

Title:
  Elantech touchpad moves and clicks by itself

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I am facing a very annoying hardware problem. It's so bad tha it makes
  hard even to report it: the mouse (touchpad in this case) keeps moving
  to the left side of the screen and clicking by itself. So all the
  programs on the Unity sidebar are keept being opened until the system
  gets without memory and very slow.

  Since the hardware is a relatively new ultrabook, I tought a newer
  kernel could had solve this issue, so I upgrade to saucy. Everything
  worked well after the first boot which followed the upgrade but after
  rebooting again the same thing started to happen.

  That's the device ID given by lsusb command:

  Bus 003 Device 003: ID 04f3:0035 Elan Microelectronics Corp.

  I also thought it  could be a problem with the touchscreen, but dmesg
  gives me a lot of error messages for the touchpad, with seems to be
  recognized as a psmouse. Installing gpointing-device-settings package
  and openning the config tool shows no touchpad related options.
