hello!
i am trying to enable cuda on blender and nothing worked to far
i tried different drivers (331 340 346) and different blender ver (2.69 2.71 2.72)
and still nothing
i am using linux mint 16
(i installed the nvidia-cuda-toolkit)
and i am using Nvidia 660Ti
can someone tell me what am i doing wrong or what am i missing?
thnx
Make sure you are using cycles, BI doesn’t support CUDA.
I fell into this trap, too. I could have sworn BI had CUDA support, but it must have been:
(sigh)
i am using cycles but still nothing is there only cpu option :c
Have you selected your graphics card in the User Preferences / System / Compute Device setting ?
it doesnt show it
it says compute devience None and from the list CPU
there is no cuda anywhere
there is no option for cuda there
there is only None-CPU
Please you show here what you get from the terminal with the next commands:
lspci | grep -i vga
sudo dpkg -l | grep -i nvidia
Are you able to open nvidia-settings?
You find and install the “nvidia-modprobe” package. Then reboot the system.
Are you using blender from repositories, or downloaded official Blender?
Like YAFU said, you need to install the nvidia-modprobe package. I had no CUDA option until I install that.

nvidia settings are working fine
i used the blender from repo but now i unistalled it and i have only the 2.72b from the official site
i am not sure what nvidia-modprobe is i dont think i have that package now and i cant install it from apt-get maybe u typed it wrong?
I do not know with what version of Ubuntu corresponds mint 16. You download the file from here, install and reboot:
http://packages.ubuntu.com/trusty-backports/nvidia-modprobe
Edit:
Oh, you’ve installed the driver from xorg edgers, so that file should work.
As always recommend, you disable Xorg edgers PPA from your software sources manager after installing the driver.
ops i have linux mint 17 i just upgraded it
i disabled the xorg ppa still dont know what to do :c
do u want me to try with 340 driver? (this was the one i had when i tested it on blender 2.71 and it didnt work either)
Have you finally installed the nvidia-modprobe package, and then restart the system?
sudo dpkg -l | grep -i nvidia-modprobe
You could try enabling the PPA again and installing 343.22 version. But remember install “nvidia-modprobe” package too.
sudo apt-get install nvidia-modprobe
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package nvidia-modprobe
when i do
sudo modprode nvidia there are no errors
Ops i posted the same thing twise sry
That is, you open the link. Under “Download nvidia-modprobe” click in “amd64” file. Then you click on any of the links that appear below and the browser will give you the option to inatall (maybe) or download the .deb file. If you choose to download it, then open the file browser, you find the file called “nvidia-modprobe_340.24-1~ubuntu14.04.1_amd64.deb” you have downloaded, double-click on it and install it.
oh never mind it worked even with 346 drivers on thnx man ! now i can get to work 
Good to know this is working now! 
Installing nvidia-modprob can help you or may be no. The simple answer of the activating Cuda option is the manual installing Nvidia driver. Do not use PPA or Linux Setting like Additional Drivers, instal deb package from Nvidia official site. Look instuctions from ubuntu official.
