Hi, Maybe the troubleshooting or the "hard way" pages have something useful: https://en.opensuse.org/SDB:NVIDIA
(I use Ubuntu and Mint, so can't help you more. Years ago I collected some info from the mailing list, but it's both old and mostly Ubuntu-specific: http://tech.kovacs-telekes.org/2014-07-29-darktable-opencl-nvidia-ubuntu-1404-mint-17 ) Kofa On 7 Aug 2017 08:40, "David Vincent-Jones" <[email protected]> wrote: Yes, I have a nvidia card. (Quadro K1000M) I installed and ran clinfo but the dt core options still shows opencl not available. searched for nvidia-modprobe and it is not found. I used the fairly simple opensuse install procedure (which worked well on the previous release) and to make sure I ran the process again including a reboot. Any idea where I should go from here?
