(Note to myself: collect this info in bug-control, and the installed icds, too, and /etc/OpenCL/vendors in bug-script) Please install the ocd-icd-libopencl1 and clinfo packages from stretch. unload the nvidia-uvm module (nvidia will stay loaded, so X can continue to run) (as root) # modprobe -r nvidia-uvm and now try clinfo (on the nvidia platform only) to see whether the nvidia-uvm module is loaded automatically (as user) $ OCL_ICD_VENDORS=nvidia.icd clinfo $ dmesg | tail That worked for me, i.e. nvidia-uvm got loaded automatically. If that works, try again unloading and start darktable with OCL_ICD_VENDORS=nvidia.icd set Andreas
