And the output of the following might help, too:

  for e in /sys/class/input/event*; do udevadm test-builtin keyboard $e;
done

Title:
  Latest systemd updates break touchpad disable hotkey on Dell laptops

Status in “systemd” package in Ubuntu:
  In Progress

Bug description:
  The latest update to systemd in 13.10 seems to have broken the
  touchpad disable / enable hotkey on Dell laptops.  This so far
  includes the Latitude series (E6430, 6430u, E6530, etc), Precision M
  (M6700, M4700) and some of the newer Inspiron laptops.

  The Latitude and Precision models use the Fn+F5 keystrokes to turn the
  touchpad on and off, while Inspiron uses Fn+F3.

  I verified before updating that the hotkeys worked properly.

  All other hotkeys on these laptops are unaffected.  They still work
  fine.

  Steps to reproduce:

  1) Before updating systemd, verify the Fn+F5 or Fn+F3 keystrokes successfully disable and enable the touchpads. 
  2) Update to latest systemd
  3) Try the hotkeys again.  

  Actual results:
  hotkey stopped working

  Expected results:
  hotkey should continue to work

  In the older udev release we added some rules to 95-keyboard-force-
  release.rules for Dell machines because many of them had issues with
  releasing key events.   Not sure if we need to do something else for
  these laptops with the new package.
