Same question as on the Blender stackexchange site.
As a recap:
- I have to install the nvidia driver but how to do it? (repository or manually? And I already had problems with both, as said)
- My computer detects an other graphic card as the one that I have! (Maybe the reason why no proprietary drivers are purposed)
Every help is welcome!
It came out that the problem was that I have OPTIMUS. But in 14.04 it seems to be supported.
So, under 14.04 (on my external HDD) it detects my Nvidia driver OUT OF THE BOX!!!
But with Blender and cuda installed as said on this site and this driver:
I then installed Blender from this ppa as well as the CUDA driver from the same site.
Then, Blender detects the GPU!!!
But it says (Cycles mode with GPU rendering active):
Even with Experimental on:

UPDATE
This all seemed to work until I tried to render, but then I got
Then on the console:
Installing CUDA 6.5 involved completely installing
nvidia-337
(otherwise you get a lot ofcuda-6-5 : Depends: .... (=....) but it is not going to be installed.
(as shown here) and instead installingnvidia-340
.To install this nvidia-340,
Other sites (AskUbuntu on Lubuntu, R Tutorial, etc) recommend installing from the
.run
, but I had no issue just usingapt-get
. The process did archive (rename) my xorg.conf file which disabled my edit file, but that was simple to revert.
