Same problem on my R510J (X550) Asus laptop with Kubuntu 14.04. The touchpad works only as a standard mouse and is very difficult to use whith accuracy : the cursor moves as soon as I try to click... I have to touch only the very edge of the pad to succeed. No scroll, two-fingers click and other features. No possibility to change settings : "no Synaptics driver loaded" message in SystemSettings.
WIth an external usb mouse everything is ok.
