Touchpad fix on dell xps 13 9360

Dell XPS 13 and 15 laptops with Ubuntu 16.04 installed, you may experience an issue with the touchpad where the cursor behaves erratically and jumps around on the screen.
This is caused by multiple drivers loading in the Ubuntu 16.04 environment. This issue can be resolved by blacklisting, or disabling, one of the drivers through a terminal
