The example configuration below shows how to use three screens with Xinerama, two external with the NVIDIA card and the internal with the intel card. You can use your internal monitor (connected only to the intel card) and some external monitor (Connected to the NVIDIA card) together with Xinerama. If Bumblebee is correctly configured, your NVIDIA-Card should wake-up when you start the secound X-Server and if you kill it, it should be going to sleep again.Д®xample X.org-Configuration using Intel and NVIDIA together This minimal configuration should detected the connected monitor and use it automatically. With a minimal xorg-configuration for your NVIDIA-Card, as example: Xorg :9 -config $path-to-nvidia-org-configuration-file -nolisten tcp -noreset -verbose 3 -isolateDevice PCI:01:00:0 -modulepath /usr/lib/nvidia-bumblebee/xorg/,/usr/lib/xorg/modules

A better solution is to activate the NVIDIA-Card only when you connected to an external monitor.ДЄfter that you can start a secound XServer on your NVIDIA-Card (replace the $path-to-nvidia-org-configuration-fileВ !): You can solve this problem by switching completly to the NVIDIA card in the BIOS settings, but this uses more battery power.

So you cannot use a monitor via DisplayPort/DVI with the integrated graphics card (Intel). It seems that the digital video ports (DVI or DisplayPort) only connected to the NVIDIA-card (Only if you have one, of course, see ThinkWiki - Switchable Graphics and Docks). Note: This solution may work on other devices with NVIDIA-Optimus, too.
