Default Re: Optimus support for Linux

Yes, the first generation quad-core had no integrated graphics but the second generation does (

It is clearly stated in the new CUDA SDK documentation ( that some laptops do contain an option to disable integrated GPUs (at least that is my impression) as seen in the quote below. The latest drivers 270.41 are stated to support Geforce 540M that I have.

"Some designs incorporating supported GPUs may not be
compatible with the NVIDIA Linux driver: in particular, notebook and
all-in-one desktop designs with switchable (hybrid) or Optimus graphics will
not work if means to disable the integrated graphics in hardware are not
available. Hardware designs will vary from manufacturer to manufacturer, so
please consult with a system's manufacturer to determine whether that
particular system is compatible."

Where can I buy such a laptop that can disable the Intel integrated graphics? Does it exist or is NVIDIA referring to a parallel universe that we cannot reach?

Thanks in advance.
