I know there are a lot of threads concerning CUDA and GPU-rendering in Blender, but I haven't figured out yet why my installed Blender(2.70) from the repository offers no choice of the rendering-hardware but the bundle you get from blender.org does?
I'm currently using Linux Mint 16 64bit but I observed that fact on Ubuntu 12.04 as well. But on Ubuntu 14.04 the CUDA-option is active on both versions of Blender.
So my system has the necessary drivers to go on with the GPU, the question is, where do I start to fix the repository version, cause I'd like to link the blend-files..
