Thanks for your quick feedback! After installing the GPU (OpenCL) compiler and support for my card (NVIDIA): Setting up libnvidia-compiler:amd64 (304.64-2) ... Setting up nvidia-opencl-common (304.64-2) ... Setting up nvidia-opencl-icd:amd64 (304.64-2) ... I have: $/opt/darktable/bin/darktable -d opencl [opencl_init] trying to load opencl library: '<system default>' [opencl_init] opencl library 'libOpenCL' found on your system and loaded [opencl_init] found 2 platforms [opencl_init] found 2 devices [opencl_init] discarding CPU device 0 `Intel(R) Core(TM)2 Extreme CPU Q9300 @ 2.53GHz' as it will not deliver any performance gain. [opencl_init] device 1 `Quadro FX 770M' doesn't have sm_20 support. [opencl_init] discarding device 1 `Quadro FX 770M' due to insufficient global memory (511MB). [opencl_init] no suitable devices found. [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system. [opencl_init] initial status of opencl enabled flag is OFF. So, this time it looks like a dead-end, right? Not enough memory on my graphic card (Notebook DELL M4400, with Nvidia FX 770M) :( Pascal. -- Pascal Obry / Magny Les Hameaux (78) The best way to travel is by means of imagination http://v2p.fr.eu.org http://www.obry.net gpg --keyserver keys.gnupg.net --recv-key F949BD3B ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
