Here is how I stopped my Macbook Pro’s touch pad from jumping around when I’m typing. This is on openSUSE 12.1 and my Macbook Pro 5,3 (2009).
In my home directory I have a scripts directory for various things so that is why it is here…
/usr/bin/syndaemon -t -k -i 2 -d &
Then I add this to “autostart” in KDE as a script.
