Preferences panel is not visible

[Raffaello Manacorda]

On Linux Mint 16, clicking on "preferences" does not open the preferences panel, furthermore the option becomes greyed out. However clicking on disable touchpad works flawlessly.

Output from the command line when clicking on the preferences command:

Couldn't find synaptics properties. No synaptics driver loaded?
