[xmonad] Extra keyboard

[Jean-Baptiste Mestelan]

Hello,


I have a USB numeric keypad lying about, and would like to use its
keys as special shortcuts (like, its Num-6 could simulate
XF86AudioNext...).
How do I tell its key strokes apart from those of the main keyboard?
Is this done at X level?
Would the helpful people on this list provide some pointers, or set me started?

Thanks for attention.

* FWIW, here is dmesg:

You'll need to use the XInput extension (x11-xinput package), as X11 core
only understands a single keyboard so by default all system keyboards are
treated identically and their events mixed into a single event stream.

Many thanks, Brandon; looking into that now.

Just in case the question was more specific than it needed to be, it's
possible the numeric keypad reports different keys than the "number keys"
at the top of your normal keyboard anyway. X distinguishes between xK_6 and
xK_KP_6. So if you don't normally use the keypad on your main keyboard,
this can be an option.

Many thanks, Daniel, for your notice.
You are quite right that my numeric keypad reports distinct keys, and
I should have realized that, since they do not toggle workspaces.
So i might even get away with a single keyboard.

Thanks again (and sorry for the late reply).
