I'll take a look at it. I have no use for Optimus - I just need a laptop with basic CUDA support. The model I unwittingly got was an Inspiron, and there didn't seem any way to disable Optimus. I'd love to be wrong (no RMA until after the holidays so it's not out the door yet) but I saw no options in the BIOS. I'm used to not being able to use the bleeding edge features in Linux, I'm just not used to being shut out completely, at least by nVidia products.
