I've a problem with GPU activation in blender. I've found same problem here already, however it didn't help.
I've a GeForce 750Ti graphics card with proprietary drivers installed (not from site but from repo) version 334.
I've also installed nvidia-cuda-toolkit package. Nothing helps.
Is there any way to run blender in a verbose mode from console to find out what's wrong in cuda detection?
Note that questions about OS/driver configuration (i.e. not about Blender) are off-topic here." – gandalf3 Jun 05 '14 at 19:35
