我按照这些步骤在 16.04 版本的 ubuntu 系统中安装了 nvidia 驱动程序 440。我的显卡型号是 nvidia GeForce GTX 1080
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
当我做ubuntu-drivers devices
它显示像
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
manual_install: True
modalias : pci:v000010DEd00001B80sv000010DEsd0000119Ebc03sc00i00

在上述输出中，驱动器440不存在。
sudo apt-get install nvidia-440
