Datadog: As Travis has already pointed out above - this is a packaging issue with the Ubuntu drivers. Therefore, it isn't downgrading from 169.12 to 169.04 which has fixed it for you. It is fixed because you've installed the version direct from NVIDIA as opposed to an Ubuntu packaged version. It would also probably work if you installed 169.12 direct from NVIDIA.
