Christopher,

Dell community forum is monitored by Dell employees that can pass the
info to their engineering team so that they can investigate this
further. So what I'm doing is more purposeful than nagging people about
opening a new bug report with info that you already have. *IF* it is a
BIOS/firmware/EC bug there is no point in opening yet another bug report
for an issue that can't be resolved in Linux!

Title:
  [Dell Latitude E7440] ALPS touchpad keeps having state reset

Status in linux package in Ubuntu:
  Incomplete
Status in linux package in Fedora:
  Unknown

Bug description:
  The mouse cursor keeps on jumping around, and these messages appear in the log when it happens:

  The touchpad is recognised as a "AlpsPS/2 ALPS DualPoint TouchPad".
  This is occurring with Ubuntu 13.10, though I have also seen this
  behaviour in the version of Linux Mint based on Ubuntu 13.04.
