Hello,
I recently upgraded my unraid from 7.0 to 7.1 latest version. after upgrade my NVIDIA GPU having issues and all docker containers using this NVIDIA GPU did not start and getting runtime error. Then i looked at the driver utility and i saw "ERROR: No driver found!". I also tried to revert back to 7.0 version and now i am still getting same GPU and app install issue in that version as well. I also tried to reinstall NVIDIA Driver utility manually but still not resolved. I also tried all possible solution available online including this tread but no luck. Note: I do see NVIDIA driver showing available in the system devices so ruled out the physical issue with NVIDIA GTX 1660 SUPER card. I am stuck now and all my key docker containers are down due to GPU not being available.
