Comment 3 for bug 1311362

Thanks for reporting this The Bright Side, but this issue is much bigger than darktable.

The fact that clinfo gives a weird error is a good indicator that this is a very general problem, not related to any user-land programs. The reason I found it (again, thanks) was that I have a problem with boinc-client. As soon as I upgraded to 14.04, boinc-client stopped being able to detect any OpenCL resources.

This is an OpenCL driver problem with the nVidia drivers.

I think this is link is relevent, which says to install nVidia drivers manually:

I'm just trying to figure out if that is worth doing or if Ubuntu folks are going to fix it soon.
