This is very unlikely, something else is probably going on. For completeness, this error is thrown by the CUDA driver during its initialization. CUDA.jl has done nothing at this point, so no change there could influence whether this error gets thrown or not. I suggest you verify your set-up, e.g., see if nvidia-smi reports the GPU, check dmesg for NVIDIA-related errors, try the deviceQuery sample from the toolkit, etc. It’s much more likely that you, e.g., upgraded your kernel and the NVIDIA module didn’t recompile (I can’t imagine you not having installed any update over the course of the last year).
