Public bug reported:

Equipment:

* Fujitsu/Siemens Amilo M3438G laptop
* Logitech DiNovo MediaPad via bluetooth


Short summary:

Putting the Logitech MediaPad in numerical mode also toggles Numlock,
making laptop keyboards with numerical keypad emulation on the regular
keys unusable. Logitech MediaPad should not toggle hardware Numlock, but
input should still be recognized properly.


Longer description:

The MediaPad is basically an external numerical keypad. The laptop does
not have a separate numeric keypad, but uses numlock to toggle some
regular keys to numeric mode. So I'm using the MediaPad for this
instead.

The keypad has three "mode" buttons: numerical, navigation and
calculator (the last one is built in and does not communicate with the
computer).

Problem is that, when I put the MediaPad into numerical input mode,
Ubuntu takes this as toggling Numlock on (and navigation takes it off),
which means that when using the MediaPad I can't use large parts of my
laptop keyboard normally.

So, I would like to be able to use my MediaPad in numerical mode without
toggling hardware Numlock.

I'm sure this could be solved technically, by noticing (via udev?) that
it's a MediaPad doing the toggle and doing some remapping.

What I'm not as sure of is if it would have any other implications for
applications, if anything needs to know that Numlock is toggled or not
(for input of numbers vs navigation, that is).

When using either a laptop or the DiNovo regular keyboard, there is no
conflict with those since they don't have a numeric part, and I would
think that it would be extremely uncommon to use a full-size keyboard
and the MediaPad together, since that would, well, not make any sense.
