How to purge and reinstall bumblebee completely?

Question

I have had bumblebee working since 13.04. It took me some messing around though and now on 14.04 it is not working anymore.

How can I purge it completely and reinstall it?

I recommend looking into installing the proprietary drivers and nvidia-prime if you are using 14.04. It finally supports optimus and you can switch your graphics card via an additional indicator. For me the performance is much better using nvidia-prime. In this thread the installation is explained quite well: How do I get switchable graphics to work on my Samsung RF711 With Intel HD & GeForce 540M Graphics cards on Ubuntu 14.04 LTS
