Belnder cant find my GTX 780 ti

Hi I´m quite new to Linux and I need some help.

I got everything running under SolydX except my cuda cores. I have installed the cuda tool kit as Nvidia´s support says (sudo apt-get install nvidia-cuda-toolkit).
But it says that by installing you should be able to choose if you whant to keep or replace your old drivers (https://developer.nvidia.com/cuda-downloads#linux). I didn´t get this option.

I got Linux-x86_64 with Nvidia 331.67 drivers installed.

When running inxi -Gxx I got this:
Graphics: Card: NVIDIA GK110B [GeForce GTX 780 Ti] bus-ID: 01:00.0 chip-ID: 10de:100a
X.Org: 1.15.0 driver: nvidia Resolution: 1920x1200@60.0hz
GLX Renderer: GeForce GTX 780 Ti/PCIe/SSE2 GLX Version: 4.4.0 NVIDIA 331.67 Direct Rendering: Yes

So to the point, I want to use the cuda cores for Blender and Aftershot Pro 2. To speed up things. And I would really need some help!

Thanks

I’ve just installed nvidia driver and cuda package on Archlinux.
After that, rebooted, go to blender preferences, set my gpu card instead the cpu.
And in Cycles render, I can choose the GPU render, and it works.

No luck with that
