[ubuntu18] install Nvidia driver

安裝 nvidia driver
試過幾種方法，最後還是覺得用apt來安裝比較妥當 先新增repository、update、裝driver

$ sudo add-apt-repository ppa:graphics-drivers/ppa
$ sudo apt update
$ sudo apt install ubuntu-drivers-common
然後用這個指令

$ ubuntu-drivers devices
看一下現在的驅動程式狀態

administrator@hqdc032:~/pg-strom$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001288sv0000174Bsd0000326Bbc03sc00i00
vendor   : NVIDIA Corporation
model    : GK208B [GeForce GT 720]
driver   : nvidia-driver-410 - third-party free
driver   : nvidia-driver-418 - third-party free
driver   : nvidia-340 - distro non-free
driver   : nvidia-driver-430 - third-party free recommended
driver   : nvidia-driver-390 - third-party free
driver   : nvidia-driver-415 - third-party free
driver   : xserver-xorg-video-nouveau - distro free builtin
我這張卡，可以裝到 430 的版本， 接下來就繼續安裝驅動程式、裝完之後重開機

$ sudo apt install nvidia-driver-430 
$ sudo reboot 
這時候，應該可以看到一些基本資訊

$ lsmod|grep nvidia 
大概長這樣

nvidia_uvm            798720  0
nvidia_drm             45056  3
nvidia_modeset       1093632  7 nvidia_drm
nvidia              18194432  258 nvidia_uvm,nvidia_modeset
drm_kms_helper        172032  1 nvidia_drm
drm                   401408  6 drm_kms_helper,nvidia_drm
ipmi_msghandler        53248  2 ipmi_devintf,nvidia

查看：
$ nvidia-smi

到這邊 nvidia 驅動程式安裝完成，接下來安裝 cuda
