**System Information**
Kubuntu 14.04 Linux-x86_64
**Blender Version**
Broken: 2.71 09b0ead
Worked: Well, it has worked with the previous graphic drivers that I had installed. (331.38)
**Short description of error**
Just starting Blender (cycles by default) I get this message in the console:
CUDA cuInit: Unknown error
Everything else is working well. You know, some games and Blender itself is working fine but the gpu rendering mode is gone. So I think it has to be some bug in Blender.
I've found some references about this problem:
1- https://developer.blender.org/T39149
2- https://bbs.archlinux.org/viewtopic.php?id=178076
Both of them related to a module that I've installed and loaded named nvidia-uvm.
And I've tried to do what they say but it hasn't worked.
