Hello Linux Geeksters. In this article I will show you how to enable natural scrolling on Ubuntu 13.04 Raring Ringtail, Ubuntu 12.10 Quantal Quetzal, Ubuntu 12.04 Precise Pangolin, Linux Mint 15 Olivia, Linux Mint 14 Nadia and Linux Mint 13 Maya.

The easiest way to enable the Mac OS X style natural scrolling on Ubuntu and Linux Mint, without needing to do tweakins or edit configuration files/menus, is to install the natural scrolling package.
Add the PPA:
$ sudo add-apt-repository ppa:zedtux/naturalscrolling
Update the system:
$ sudo apt-get update
Install Natural Scrolling:
$ sudo apt-get install naturalscrolling
Just enable it from the Unity dash, or from the applications menu. Natural scrolling can be turned on and off, from the app-indicator menu.
