[David Marsh <dmarsh26@xxxxxxxxxxx>]

As I understand it there are two options :-

1. Install closed source binary driver from NVidia and have GPU on 100% of the time.

2. Install noveau open source driver and have possibility of :-
    2.1 Intel GMA + NVidia GPU for CUDA/OpenCL.
    2.2 Just Intel GMA with NVidia GPU turned off / powered down ?

NVidia have stated they do not intend to support Optimus for Linux.

I think people are hoping to at some point have a runtime switch similar to either the old manual user switching or the automatic Windows Optimus switching supported in noveau.
There appear problems with the design of X Windows and the fact the the NVidia code is closed source however, so this may never happen ?

So the answer to his problem would appear to be install the closed source binary driver ? However this will result in poor battery life.

Correct me if I'm wrong as I'm a relative linux noob and not an expert on the Noveau code.

regards

David M

You are not really answering him.
He wants to use his nvidia card, not to shut it down.
I saw only one interesting mail about this real issue on this mailing list, and 
no one ever answered this mail :

I hope we hear a lot from this johnny and I really hope he'll succeed.
To sum up for f_dav : so far, no way to use your nVidia card, you can only shut 
it down using this acpi_call thing.
