Thank you for the explaination, I asked because I had some users with AMD hybrid graphics having issues with that, so I wanted to know if whether bumblebee could work with radeon open source drivers or was tied to Nvidia + Intel. I hope the situation with AMD hybrid to improve in the future, thanks to this project.
