简单一步在ubuntu18.04下nvidia driver的安装

推荐这里，安装方法简单来说就一步：
sudo ubuntu-drivers autoinstall

细节
但是如果你要是想要知道自己细节可以继续看

查看NVIDIA的驱动有什么
ubuntu-drivers devices

你可能看到的结果是这样的
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001180sv00001458sd0000353Cbc03sc00i00
vendor : NVIDIA Corporation
model : GP106 [GeForce GTX 1060 6GB]
driver : nvidia-304 - distro non-free
driver : nvidia-340 - distro non-free
driver : nvidia-390 - distro non-free recommended
driver : xserver-xorg-video-nouveau - distro free builtin

== cpu-microcode.py ==
driver : intel-microcode - distro free

安装NVIDIA驱动
sudo ubuntu-drivers autoinstall

或者
sudo apt install nvidia-340

然后应该重启一下就好了，
如果你需要最新的驱动
当然如果你也是使用cuda玩神经网络的话，tensorflow1.11是要求NVIDIA410的版本才行，那么你需要最新的驱动
可以先增加一个ppa
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update

然后
ubuntu-drivers devices

你可能会发现还有一个新的NVIDIA驱动
可能是这样的
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
