Touchpad on Lenovo 500X Ideapad is "touchy"

[frogprince]

Hi, I'm running Ghost on a Lenovo 500X Ideapad. The touchpad is, well, touchy, and there's only two parameters available through the MATE client, acceleration and sensitivity. Neither goes quite far enough. In Linux, the synaptics touchpad driver gives access to multiple other parameters via a command line application. I do have xf86-input-synaptics installed, but I don't find a touchpad.conf file as per

Where in Ghost is the touchpad driver information stored? Is there a file I can edit, or ??? Thanks in advance.
