I am using the latest version of ubuntu 14.04 in the new lenovo Z510 ideapad laptop. I came across this problem while i was trying to enable my two-finger swipe action. Usually the mouse and touchpad setting will have separate columns for mouse and touchpad as shown here:

Whereas in my case there is no two parts. Just one, as shown.
Now can I get my settings back to normal, as shown here? Also, is it possible to enable both edge scrolling and two-finger scrolling without the use of third party apps like touchegg? If so, how?
