можно начать с xev
Я не совсем корректно выразился, похоже. Система именно *не видит* кнопку.
Вот вывод xev:
artiom@dana ~$ xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'
36 Return
65 space
^C
Я нажимал на кнопку камеры.
Аналогично:
root@dana:~# showkey -s
режим kb был ?НЕИЗВЕСТНО?
[ если вы пытаетесь проделать это под X-ами, то, возможно,
это не сработает, так как X-сервер тоже читает /dev/console ]
нажмите любую клавишу (программа завершается через 10 секунд после последнего
нажатия на клавиатуре)...
0x9c
0x39 0xb9
0x1d
^Cпойман сигнал 2, очистка...
Проблема в том, что "аппаратная кнопка" не видна на "уровне устройства" (или не
понята udev):

Как сделать так, чтобы этот "Miscellaneous Device" был понят, как кнопка?
