На недавно созданной машине Ubuntu 16.04 работает nvidia-smi не работает как обычный пользователь
$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Запуск под root работает
$ sudo nvidia-smi

Есть ли неправильная конфигурация, которая требует nvidia-smi должен быть запущен сначала пользователями root, и есть ли решение для этого? например вручную загрузить модули ядра NVIDIA
