thanks, Šarūnas,

I have two Darktable systems, based on Lenovo TS140, one with AMD, the other with Nvidia Quadro 400.
Neither of the two manage OpenCL..

0.039390 [opencl_init] found opencl runtime library 'libOpenCL'
0.039412 [opencl_init] opencl library 'libOpenCL' found on your system and loaded
0.042560 [opencl_init] found 1 platform
0.042582 [opencl_init] found 1 device
0.042727 [opencl_init] device 0 `Quadro 400' has sm_20 support.
0.042778 [opencl_init] discarding device 0 `Quadro 400' due to insufficient global memory (511MB).
0.042784 [opencl_init] no suitable devices found.
0.042788 [opencl_init] FINALLY: opencl is NOT AVAILABLE on this system.

I would like to upgrade one of the two systems to a 4K display, so was already decided to purchase a new video card.

Is there a tested solution that works out of the box, or a list of DT OpenCL compliant cards for Linux?

Hello All,

DT 3.2.1 here, running on Ubuntu 20.04, Radeon HD5400.

OpenCL should be working, however DT complains "could not get platforms"
(see below).
Support for Radeon HD5xxx may have ended with fglrx (Ubuntu 16.04?).

You may check what is currently supported,
