I'm copying a message from Nicolas Thierry-Mieg below. Hope this helps
you figure out why things are not working.

"you might have some useful info in /var/log/Xorg.*

I had set up bumblebee on my son's laptop in the past and had to move
some things around, because [some reason, can't remember the details
but it was something like X not looking in the correct folders for the
2 cards]. Carefully reading through the Xorg.* logfiles had allowed me
to find the source problem. I can look it up one of these evenings if
needed."
