CUDA.jl initialisation fails after suspending Ubuntu 20.04 with CUDA 11.2 #605

Something isn't working

Error 999 is your driver being messed up. Nothing we can do about that. |
Ah I forgot to close this issue. I started to manage multiple CUDA environments when I tried to play with CUDA.jl, so I deleted the lines that add paths automatically. Somehow before I suspend the system Julia can find the path, but not after. |
