I just upgraded to Darktable 4.6.0 and am suddenly getting an error message on startup:
OpenCL initializing problem:
Platform detection failed, some possible causes:
OpenCL ICD (ocl-icd) missing
previous OpenCL errors leading to blocked devices
Power management problems
buggy drivers
no OpenCL driver installed.
I am on a Dell XPS13 with an Intel Core i7-7500U CPU @ 2.70GHz × 4 processor and a Mesa Intel HD Graphics 620 (KBL GT2) graphics card running Ubuntu 22.04.
Need to ponder how important GPU perf. is then. If so it’s looking like 15.6" laptops instead of more portable ones - or a portable plus a desktop box of sorts.
For me it’s important to have O-CL running. For several weeks now I’m w/o O-CL on my Linux-Box (Garuda Linux, current kernel and dt 4.6.1 don’t like each other any more). I have no knowledge how to fix this. But, that’s an other story.
My DELL notebook ist currently with me (easter holidays) and I use it for backup purpose and a quick culling of daily captures. Because of lack of O-CL I only use lens correction module to get some colors from the RAW files. That’s quick enough.
Current Intel CPUs mostly have their GPU supported with opencl in darktable. My 5y old 8GB X1 lenovo works fine on linux, OpenCL is not very fast but ok.
OK, I’ll try to get DT out of the Chrome OS container and onto the metal, maybe the UHD 605 (OpenCL 1.2) will beef it up then. It’s not unusable as it is but worth a try.
