Hi Bruno, thank you for getting back to me. That's frustrating to hear that
integrated nVidia can't be handled in the same way as Intel. Will bbswitch
work to turn off the discrete card, however? Or should I use the acpi_call
module with the call I mentioned (described here:
http://luizfar.wordpress.com/2010/06/29/how-to-switch-off-xps1340-discrete-video-card-on-linux/
)?

Also, are there known ways to force X to use the discrete card full-time
rather than the integrated chip? Do you know if there's some way I can
research ACPI calls or whatever it may take to do this? I'm not quite sure
where to begin.

Thanks,
Michael
