Title:
  Touchpad on Alienware M15x goes nuts, needs psmouse-ectomy to quiet
  down

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  This is pretty much guaranteed to happen at some point after each
  reboot.  The touchpad will behave (it's not really used as I almost
  always use an attached Logitech USB Wireless Mouse) as it should for a
  while and then at some point the pointer starts going crazy, jumping
  left and right over and over.

  There doesn't seem to be any specific trigger, it just happens, and
  there doesn't appear to be any specific time frame either.  Sometimes
  it happens within an hour of a reboot, sometimes it can take a day or
  more.  But once it happens and the pointer starts jumping left and
  right on it's own, the only cure is to rmmod psmouse.

  I can reload psmouse and be OK for a while, but invariably, the
  twitchy pointer returns.

  This is a regression in one of the recent kernels for Oneiric.  I have
  had Ubuntu on this system since Karmic and have never experienced this
  issue until a couple months or so ago with an Oneiric update.  In
  fact, I do not recall experiencing this with the original Oneiric
  released bits.
