Default Re: No Optimus support means NO Nvidia at all or no dynamic switching?

I am preparing a short seminar about Cuda programming at my university and i am not able to test my example programs und compare the performance with the same CPU -programs. Unfortunately i have to give the information that many nvidia-laptops are not usefull for scientific programming under CUDA because they are not able to use Linux. So please Aaron if you can give us a hint how we can use CUDA, give it!

It doesn't work see:

So basically if you want to use Linux don't buy an Optimius Laptop (yet?).
