Finally, relevant to debugging - I see the following in the dmesg logs on startup:
lws@daedalus:~$ dmesg | grep i2c [ 11.983106] i2c_hid i2c-SYN1B7F:01: failed to retrieve report from device. [ 11.991460] i2c_hid i2c-SYN1B7F:01: failed to retrieve report from device.

The default settings assume that the ClickPad is just a normal touchpad with a single hardware mouse button. Basic touchpad functionality is OK. Multitouch features such as two-finger-tap to right-click, and two-finger-swipe to scroll, do work. However, clicking and dragging with the hardware click button, and right-clicking with the hardware click button, do not work. `xinput --list` reports the touchpad as `SYN1B7F:01 06CB:2991 UNKNOWN`. Tweaking settings using `synclient` can fix the problem. For example, to set up the bottom right-hand corner of the touchpad as the software right-click button, we can do the following at a command line: synclient ClickPad=1 synclient RightButtonAreaLeft=610 RightButtonAreaRight=1175 RightButtonAreaTop=489 RightButtonAreaBottom=648 (This configuration is not perfect, and does not persist between reboots - `xorg.conf` editing probably needed for that.)
