Thanks for the response Pascal. In my core options Activate OpenCl is switched on, what I don't have is an option to turn it off.
Since I didn't understand the problem at all, I'm afraid I never even noticed that troubleshooting option in the manual. Looking at it after your message, it does seem to give some explanation of my problem. But the system was working fine until two weeks ago, with no settings changes. So I tried darktable -d opencl and got [opencl_init] opencl related configuration options: [opencl_init] [opencl_init] opencl: 1 [opencl_init] opencl_library: '' [opencl_init] opencl_memory_requirement: 768 [opencl_init] opencl_memory_headroom: 300 [opencl_init] opencl_device_priority: '*/!0,*/*/*' [opencl_init] opencl_size_roundup: 16 [opencl_init] opencl_async_pixelpipe: 0 [opencl_init] opencl_synch_cache: 0 [opencl_init] opencl_number_event_handles: 25 [opencl_init] opencl_micro_nap: 1000 [opencl_init] opencl_use_pinned_memory: 0 [opencl_init] opencl_use_cpu_devices: 0 [opencl_init] opencl_avoid_atomics: 0 [opencl_init] opencl_omit_whitebalance: 0 [opencl_init] [opencl_init] trying to load opencl library: '<system default>' [opencl_init] could not find opencl runtime library 'libOpenCL' [opencl_init] no working opencl library found. Continue with opencl disabled [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system. [opencl_init] initial status of opencl enabled flag is OFF. So that's the problem I guess, libOpenCl is missing. Not really knowing what to do I tried reinstalling darktable, but still the same missing libOpenCL message. I've searched online and found reported issues with NCVIDIA in the mailing list archives but my graphics are Intel Integrated (Mobile 4 series), and working fine until two weeks ago. I've also searched my system for libOpencl.so and it doesn't exist (nor does libcl.so). I also ran System Update just in case. I don't know what to do or try next and although I'm a Linux user, I'm not a system guru. The manual does presuppose a fair degree of knowledge. I'm happy to cut and paste commands into terminal but I'm a point and click Linux user.
