I've been obsessed with trying to get two finger scrolling to work on my new thinkpad and have followed every howto and tutorial I've come across with no success. My configuration right now is no xorg.conf and 2 fdi files in /etc/hal/fdi/policy:

10-x11-input.fdi which sets up the keyboard
11-x11-synaptics.fdi which should configure the touchpad

After X starts I do a lshal and the touchpad is there with all options configured but it acts like it's using a default touchpad configuration. lshal reports that SHMConfig is set to 1 but when I try to run synclient -l it tells me SHMConfig is not set.

Any help would be greatly appreciated.
