Getting key codes of remote controls handled in X just using evdev and not LIRC

[Paul Menzel]

Dear X.org folks,


»In X you can use xev to find the keycodes and xmodmap to map them to
useful symbols. Unfortunately, some keys may generate keycodes that X
doesn't recognize at all and the device does not support keymaps, or
this would be easy to fix.« [1]

Do you know if there exist a solution already for this problem? Most of
the keys of the remote control (for example play, pause) do not generate
an event in `xev` on my system.

I read [2] and searched the Web for more information but did not find a
solution not involving LIRC.

At the and you will find the generated key codes by evdev.(?) Do you
know of a way to just create a keymap(?) file to map those key codes to
X events(?)?

I am sorry to ask you, but the input system (scan codes, key codes, X
mapping(?)) is still very complicated for me to understand.


Thanks,

Paul
