我正在尝试在运行 Ubuntu 19.04 的 ASUS zenbook 14 上安装最新的 NVDIA 图形驱动程序。我正在遵循本教程：https://www.cyberciti.biz/faq/ubuntu-linux-install-nvidia-driver-latest-proprietary-driver/
根据软件更新程序的窗口，驱动程序在那里：
但是当我检查驱动程序的状态时，我得到：
giulio@giulio-ZenBook-UX431FN:~$ 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.
PS. Grub 已开启nomodeset。
我如何安装该驱动程序？
我正在发布以下命令的编辑：

lsmod | grep nvidia没有输出。
答案1
驱动程序可能已安装，但 Nvidia 适配器未启用。
通过运行来启用它：
sudo prime-select nvidia
然后注销并重新登录。适配器现在应该已启用并nvidia-smi可以工作。
