I'm using Ubuntu 14.04 LTS, with a brand-new graphics card, GTX 750 Ti. I have even updated the drivers, but for some reason Blender (2.75a) doesn't seem to be allowing Cycles to render with my GPU. Even under User Preferences > System > Compute Device it says "None", with the only option in the drop-down menu being "CPU".

I'm pretty sure I purchased a decent graphics card because I bought this specially for Blender's Cycles. How can I resolve this? How do I get Blender to work with the card?

EDIT: It looks like I managed to find the answer by referring to this thread: CUDA rendering on Linux Mint or Ubuntu variants

It seems Blender won't detect the card even if I switched to proprietary drivers. In this case, I did this:

  1. Switch to proprietary drivers,
  2. Installing nvidia-modprobe by typing sudo apt-get install nvidia-modprobe
  3. Then, in the same way, I installed nvidia-cuda-toolkit

I did not need to restart the system. Just restarted Blender, and it works!

  • Ubuntu and similar Linux systems do not use the proprietary Nvidia drivers by default, but something called Nouveau (mostly for legal reasons). Cuda acceleration needed for Blender is not enabled in Nouveau and can only be used with the Nvidia drivers. –  Aug 08 '15 at 21:41

  • Yeah, I switched to proprietary drivers too, but it still wasn't working. Though, I just tried something, and I think it's detected now. – Tushant M Aug 08 '15 at 22:12
  • If you found a solution please write an answer for others who might have the same issue. –  Aug 08 '15 at 22:14
  • Yeah, I was doing just that, but it says the question has been closed. Should I simply update the question description instead? – Tushant M Aug 08 '15 at 22:17
