the touch pad of my Asus X571 seems to be not identified as touchpad when I am using the Unity desktop. So instead of the touch pad settings I am seeing only mouse settings in system configuration (Primary button, Double click speed).
However, when I start with Ubuntu (Gnome) desktop, everything is all right! Soft touch works and I can see the full touch pad configuration options.
With Unity desktop, only two-finger-scroll and the mechanical buttons are working. Soft touch is not working.
I found this page https://wiki.ubuntu.com/DebuggingTouchpadDetection but since the problem only occurs with Unity, it does not seem to be a kernel problem. Where do I start to fix this? Found many similar questions here too, but none seems to see a touchpad malfunction only with Unity desktop.
