Linux----Ubuntu 18.04：NVIDIA MX250显卡安装教程 (最新联想小新Pro 13 )_ubuntu nvidia geforce mx250显卡驱动-优快云博客

Ubuntu 对N卡不太兼容，安装系统并不能自动装上NVIDIA的显卡，需要手动安装显卡驱动软件。

联想小新Pro 13 使用的是NVIDIA MX250显卡，其他NVIDIA显卡教程也是一样的。

1. 更换国内的系统源，推荐USTC源

更改USTC软件源：

步骤：

sudo gedit /etc/apt/sources.list

替换内容

# 默认注释了源码仓库，如有需要可自行取消注释
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse
 
# 预发布软件源，不建议启用
# deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse
# deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

2. update, upgrade

sudo apt update
sudo apt upgrade

3. 加入N卡驱动源

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update

4.查看显卡驱动，会列出当前的显卡和可安装的驱动

ubuntu-drivers devices

lg6@lg6:~$ sudo ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:1d.4/0000:02:00.0 ==
modalias : pci:v000010DEd00001D13sv000017AAsd00003F19bc03sc02i00
vendor   : NVIDIA Corporation
driver   : nvidia-driver-430 - distro non-free recommended
driver   : xserver-xorg-video-nouveau - distro free builtin

5.直接安装推荐的驱动

sudo ubuntu-drivers autoinstall

6.安装完重启：

sudo reboot

7.查看一下显卡信息：

nvidia-smi

lg6@lg6:~$ nvidia-smi

如果有信息显示出来，就说明安装成功
