I've a laptop with an Nvidia optimus graphic card (GEForce GT 630m) with Ubuntu 12.04 installed. After a while of looking around, I found that the optimus controller for linus is bumblebee, so I installed it.

I would like to know whether is possible to perform GPU calculations using this driver, or Should I install the Nvidia driver? In a first try I installed the Nvidia driver, but it didn't work as expected.

Thank you!

If you installed bumblebee, you should already be using the Nvidia driver when calling the program with the optirun prefix. There is a difference though between using the GPU for applications that use the Nvidia driver and using it for CUDA. Apparently, for CUDA, bumblebee is not needed, but you need to install the CUDA relevant packages.

Thank you! I'll try to find out how to install the CUDA packages. :-) –  Dox Jul 6 '12 at 16:15
