[Bug 1343935] Re: [Samsung 700T1C-K01US] Touchpad not detected as touchpad


And some more digging...

The normal synaptics loading rule in the xorg conf files wasn't being
triggered as the "matchIsTouchpad" was failing. I tried adding an
explicit driver association to the relevant input device, and setting
the protocol to "event".

This failed like so: (from /var/log/Xorg.0.log)
