I know this is slightly larger scope than just Blender, but I know other Blender users have had this same problem. I've started using Sheep It and I really enjoy it. When I try getting points rendering on my own computer (and I have to use the .jar file because I use Linux Mint) the terminal outputs:
GPU::generate failed to load CUDA lib (path: cuda)
It still allows me to use my CPU but I could render at least twice as fast if it would recognize my GPU. I've done a little research on this and the only other guy who had this problem I could find was here: https://plus.google.com/112229882551127022642/posts/KL4QtHWHx92
And after some confusing discussion that I don't understand, Sheep It said:
The common thing between the not working system is the driver version. If you are on 331 it does work, if you are on 340 it doesn't. I have no idea why but it least I know what to look for.
What are the implications of switching between drivers? If I wanted to, how could I also install nvidia-331? What does all the confusing stuff on that Google+ post mean and would that fix my problem? Most importantly, is there any way to get my current machine, without changing my drivers, to render for Sheep It on my GPU?
UPDATE: I tried all the Drivers in the Driver Manager and none of them fixed the problem. Also, running the jar command as root does not fix the problem either.
