If a hardware mux does not exist, there there is no physical way to perform this GPU switching. Thus Optimus is used to effectively "implement" a software mux. Specifically it ensures that relevant data is sent to and processed on the right GPU then the data needed for display is copied to the device that displays the image.
When it comes to how a specific machine is configured, there are a number of possibilities. Again, if the hardware mux exists it would be used to select which GPU drives the internal panel, or the external monitor, or possibly both. It is also possible, that a GPU is hardwired to the internal panel, so the other GPU cannot possibly drive the internal panel. The same goes for external monitor output. In the worst case we have that the:the Intel GPU hardwired to the internal panel and the Nvidia GPU hardwired to the external output! The best case scenario is a mux, which can select which GPU drivers control which outputs.

Basically, you can have _any_ combination of these possibilities. There is no standard on how to wire things. There should be ways to detect the wirings and whether there is a mux and where, but the documentation is not available to the developers (maybe you can help us figure out how to do this, have any ideas? You can also 'petition' nvidia for releasing these specs: [[nvidia customer help|http://nvidia.custhelp.com/]] ? )
