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: https://devtalk.nvidia.com/default/topic/734098/linux/-boinc-ubuntu- nvidia-no-usable-gpus-found-/ I'm just trying to figure out if that is worth doing or if Ubuntu folks are going to fix it soon. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311362 Title: Ubuntu Gnome 14.04 - NVidia 331 - OpenCL broken (using Darktable) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1311362/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
