Как отключить трекпад на моем MacBook Pro с помощью syndaemon?

Я пытаюсь запустить syndaemon -i 2 -t -d, чтобы отключить трекпад во время набора текста (подробно описано в https://help.ubuntu.com/community/MacBookPro7-1/Maverick ). Тем не менее, я получаю

No synaptics properties on device 'bcm5974'.

, что странно, потому что я выполнил все шаги в руководстве. Мой xorg.conf:
