You need to differentiate between "works in console mode" and
"works in X". For the console mode, normal mouse functions will
be available, but typically Synaptics-specific things are not
supported. Technically, it is represented as a PS/2 mouse (psm),
but with extended touchpad features.

For X, you only need


in /boot/loader.conf. For the scolling feature, add


to /etc/sysctl.conf.

There are a few other settings that you can tweak:

However, don't bother with console mode and moused.

There is also the suggestion of using a partial xorg.conf entry.
While the Wiki mentions /etc/X11/xorg.conf, you'd better use
some file like /usr/local/etc/X11/xorg.conf.d/synaptics.conf
with the content as suggested:

	Section "InputDevice"
	    Identifier      "Mouse0"
	    Driver          "mouse"
	    Option          "Protocol"      "auto"
	    Option          "Device"        "/dev/sysmouse"
	    Option          "ZAxisMapping"  "4 5 6 7"

Then start X and examine /var/log/Xorg.0.log for suspicious

Having the Wiki entry match the _current_ way of making the
Synaptics touchpad work would be great.

I assume you're using moused's debugging feature? Forget about
moused and console. :-)

Correct, because now it's a "normal mouse".
