I saw this on a fedup of 21 to 22 around Beta TC3 timeframe. The problem 
was (I think) libinput not being upgraded due to a newer version in F21 
than F22, so it ended up not talking to kcm-touchpad.

rdieter and I figured it out in IRC, so there is no BZ to point you to, 
but this is as best as I can recall at the moment.
