Bumblebee with 2 dedicated video cards?

  • 772

So I have a lenovo 510p laptop, with integrated Intel HD 4600 graphics, plus 2 GeForce GT 755M-s, one of which is in the ultrabay and thus is removable. I'm running Lubuntu 13.10. I use the proprietary nvidia driver (331).

I installed bumblebee, and it seems to be working fine when the removable graphics card isn't present, however if I plug in the ultrabay, strange things happen.

Somehow it seems that the integrated intel card isn't picked up, and I have no idea, what happens actually.

Some logs:

So the big question is: is this normal? I never had a machine like before (also never used bumblebee before), so I don't really know, what to expect.

Nevertheless, the situation seems strange, and if possible, I'd like to use the intel card both cases and it would nice not having to remove the second VGA when I want a nicely working linux. Is there a way for example to completely disable/hide the optibay VGA? I wouldn't want to use it in linux anyway.
