Numpad failed on Ubuntu

Sometimes when I’ve been accessing my laptop remotely via VNC my number pad will quit working.  The number lock is on, I can see the indicator right there.  The alternate functions of the keys aren’t working either, though.  So what’s up?
Accessibility is what’s up.  For some reason unknown to me Ubuntu chooses to turn on what it calls “Mouse Keys”.  Basically when you try using your number pad you’ll notice your mouse cursor moving ever so slightly with each press of a numeral.  Here’s how to make it stop.
  1. Go to System -> Preferences -> Assistive Technologies.
  2. When the Assistive Technologies Preferences screen opens, click the Keyboard Accessibility button.
  3. When the Keyboard Preferences screen opens, select the Mouse Keys tab.
  4. Uncheck the box labeled “Pointer can be controlled using the keypad”.
  5. Close out of all dialogs.
That’s all there is to it.  Your keypad is now functional again.
