I merely meant starting a shell, and using the 'darktable' command there to launch the application, hoping that you'd get some error message printed there when darktable freezes. I also get freezes every now and then (usually after export, though), but I'm running the development version of the code, so that can be unstable; plus, my PC is ancient. > A comprehensive search on the internet returns NO 'hits' which discuss > OpenCL on Linux Mint 20 > I am using Linux Mint 20 driving an > nVidia GTX 645 OEM card, using driver nvidia-driver-455 version > 455.38-0ubuntu0-20.04.1.

The good news is, if OpenCL is disabled, it cannot cause issues (the bad news is, you miss out on performance; with a second-hand NVidia 1060, my 12-year-old machine is still usable with darktable). You say the hang-after-import is a new development. Are you aware of anything that changed? (Software upgrades, hardware changes, are you new importing a lot more photos in at once than previously? Have you cleaned your PC's inside recently? Dust can cause overheating.) Once darktable hangs, if you open another terminal and launch 'top' or 'htop' (you may have to install them first), do you see high CPU usage by darktable or is it idle? Do you see any signs indicating running out of memory? (There probably is a similar tool with a more user-friendly interface to monitor resources, but I'm not familiar with it.)
