Ubuntu Touchscreen on Lenovo Yoga 2 Pro

Does anyone have any experience with Ubuntu running on the Yoga 2 Pro in terms of the functionality of the touchscreen?

I really, really, don't see how can this be a duplicated, so I ask them here how can a totally opinion based question "what is your experience using X?" with something like:

How can I disable the touchpad automatically when I turn the monitor on the back?

A plea for sanity. This is not a duplicated!
