I have installed Fedora 20 beta on a Samsung ATIV Book 9 NP900X3F-K03SE, and the touchpad left clicks randomly and very often, so it is completely unusable. Even if I don't touch the touchpad it randomly left clicks. Below have I attached the output from xinput.

Here are videos of the problem in action
