Before having no answers, I just want to know :

Does somebody already had (even if no one know how):

1 - GPU computing working
2 - On a Nvidia GPU (850M)
3 - On a laptop who embeds an Intel HD4600

4 - but in LINUX..... !

I wonder because when looking after simple things working it's already complicated on Linux, but for this "complicated" (yeah...) thing, it seems that it is the desert. I'm beginin to think that I'm trying to do something that nobody succeeded in the past.

For 1, 2 and 3 it's already working on Windows.

I already have 1, 2 and 4 working on Linux (on 2 computers)

It seems that because of the presence of and Intel HD GPU, boinc is blinded and doesn't see the Nvidia GPU (he's able to see this same GPU when running on Windows).

I installed apt-get install bumblebee-nvidia primus and optirun glxgears -info is able to work with the GeForce 850M.

Thank you so much in advance !
