Controlling Synaptics touchpads on Ubuntu.

Even if Ubuntu is a great OS, it might have some problems on laptops with their touchpads. My laptop's touchpad is made by Synamptics, which runs, natively, on Linux, but for changing the way it responds and behaves, it needs a driver. The best way you can get it is via Ubuntu Software Center (located on Applications). Within the software center, search for "Touchpad". Click on the right button from the first result, and click install. Now, it will ask for your password (which you entered when you have installed Ubuntu). Wait for the installation to finish, then close software center, and go to System -> Preferences -> Touchpad. Now you can modify the way your touchpad moves, behaves, and others.

Tested on Dell D610 and works without problems.
