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

Oops, indeed: There are a fair number of broken keycodes, and Dell is affected by these: http:// paste.ubuntu. com/6040682/
Thanks for the report!
