I am running ubuntu 14.04 64 bit and nvidia drivers 331.38 and had the same problem of OpenCL not being available in Darktable.
This got fixed for me by a solution proposed to fix another OpenCL issue here: http://askubuntu.com/questions/449507/nvidia-libopencl1-331-has-to-be-removed-before-installing-wine?rq=1 What I did was: sudo apt-get install nvidia-cuda-toolkit and then sudo apt-get install ocl-icd-opencl-dev After a reboot, Darktable's "activate OpenCL support" is not greyed out anymore and seems to work like it should. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
