Invert scrolling of my mouse ubuntu 14.04

Let see if the mouse is emitting the right events.
Please open the Terminal application (Ctrl+Alt+T) and run the command:

xev -event mouse

A little white window should appear and there should be a lot of text in the Terminal when you enter the window with the mouse.
Now hold the mouse still while in the window and turn the mouse wheel. There should be a few lines added for every tick of the wheel.
Please check if an up movement emits a "button 4" and a down movement of the wheel emits "button 5"! Or is it also upside down?

It's called natural scrolling. You can disable it in settings

I disable natural scrolling problem still here..
