Blender GPU rendering broken with latest nvidia driver update (334.21)

After upgrading to 334.21, there is no cuda option in the user preference of blender and blender prints

CUDA cuInit: Unknown error

to the terminal on startup.

I've looked at this bug report: https://bugs.archlinux.org/task/39141, but the issue persists even after upgrading to nvidia 334.21-2.

I'm getting the same error.

I have also looked at that same bug report, oddly enough, and can confirm that the issue persists.

Did you modprobe nvidia-uvm?

According to some reports, running something (anything) that uses CUDA as root first, then running the CUDA-using app as a regular user works. Have you tried that?

I have the same problem.... after running:

By the way, with optirun just doesn't works, simply doesn't show me any other card than CPU

Did you try first with sudo?

sudo primusrun blender

Then try with your regular user.

Just FYI CUDA appeared as compute option after I ran blender as root.  I was getting the same error as OP before.

Same for me. Running as root first then as user solved the problem for the time being.

Please test the new Nvidia in testing. It should have a fix for this.

Yeah! On my System, OpenCL is useable again with darktable. Thanks!
