После ухода в ждущий режим и поднятия из него тачпад не работает. До перезагрузки иксов. Как это побороть?

если быть более точным, то после выхода из ждущего режима при тапе двумя пальцами тачпад таскает по экрану окна, одним пальцем крутит прокрутку, но курсор мыши остается недвижимым.
Проблема решается засовыванием скрипта следующего содержания -
sudo gedit /usr/lib/pm-utils/sleep.d/02touchpad
в него запихиваем:
#!/bin/bash
if [ -e '/usr/lib/pm-utils/functions' ];then
. /usr/lib/pm-utils/functions
fi
suspend_bcm5974() { /sbin/rmmod bcm5974; }
resume_bcm5974() { /sbin/modprobe bcm5974; }
case "$1" in
suspend|hibernate)
suspend_bcm5974;
;;
thaw|resume)
resume_bcm5974;
;;
*)
;;
esac
exit $?
даем скрипту право на исполнение.
