第一：安装ppa的显卡驱动源
sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
第二：检查显卡和推荐驱动
ubuntu-drivers devices
现实如下结果：
ffly@noi:~$ ubuntu-drivers devices == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd00001F08sv000010DEsd000012FDbc03sc00i00 vendor : NVIDIA Corporation driver : nvidia-driver-415 - third-party free driver : nvidia-driver-418 - third-party free driver : nvidia-driver-430 - third-party free recommended driver : xserver-xorg-video-nouveau - distro free builtin
推荐的是430显卡。
第三：安装
sudo apt install nvidia-driver-430
第四：重启并检查：
nvidia-smi
如果输出：
ffly@noi:~$ nvidia-smi Mon May 6 07:54:58 2019 +-----------------------------------------------------------------------------+ | NVIDIA-SMI 430.09 Driver Version: 430.09 CUDA Version: 10.1 | |-------------------------------+----------------------+----------------------+ | GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr.

第五：如果正常显示，则表示安装成功。
