I recently upgraded my MacBook Pro to Kubuntu 8.10 beta with the shiny new KDE 4.1. Along with this update came xorg 7.4 which does not rely on xorg.conf for device configuration anymore. From what I can tell, this is abstracted by HAL in order for the devices to be hot-(un)-pluggable.
Anyhow, I used to have many synaptics settings in xorg.conf that enabled two finger scrolling, two/three finger tapping with my touchpad. But because these settings don't go into xorg.conf anymore, here's how you can fix it (took me a couple of hours to figure out):
Create the file /etc/hal/fdi/policy/11-synaptics-options.fdi and insert the following text:
<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="input.x11_driver" contains="synaptics">
<merge key="input.x11_options.SHMConfig" type="string">On</merge>
<merge key="input.x11_options.TapButton2" type="string">3</merge>
<merge key="input.x11_options.TapButton3" type="string">2</merge>
<merge key="input.x11_options.VertTwoFingerScroll" type="string">1</merge>
<merge key="input.x11_options.HorizTwoFingerScroll" type="string">1</merge>
</match>
</device>
</deviceinfo>
This should enable horizontal and vertical two finger scrolling, right click by tapping with two fingers, middle click by tapping with three fingers.
And for good measure you might want to install "touchfreeze", a little applet that disables the touchpad while you're typing. Yay for Linux!

Eine Woche ist es nun her, dass Kubuntu 8.10 "Intrepid Ibex" veröffentlicht wurde. Und ich habe es geschafft noch im Oktober umzusteigen. Das Update wurde zwar erst nach Mitternacht. also am 01. November, fertig, aber egal. Und es funktionierte auch (fast
