Hi, I don't own a system with discrete graphics (dual graphics Intel + Nvidia)
but they are fairly common, and I'm trying to research the topic in case I need
to help a user that is switching to openSUSE.

I don't think this part is right. It makes it sound like the regular Nvidia
drivers should be installed first, and then proceed to install  the Bumblebee
stuff. I've read in several places that the regular Nvidia drivers should *NOT*
be installed on a dual-graphics system, and they can even break the X server:

This also sounds incorrect, from what I've read.



Additionally, the Bumblebee page is very ambiguous as to whether the open
source Nouveau driver can also be used with Bumblebee.

So, is it possible or not to use Nouveau + Bumblebee? If so, it would be good
to have two main sections:
1. How to configure Bumblebee with the open source Nouveau driver
2. How to configure Bumblebee with the proprietary Nvidia driver

Thanks for looking into this!
