一、 配置常用 Ubuntu 安装的阿里源：

% cd /etc/apt % sudo vi sources.list  % sudo apt update  deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse  deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse  deb http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ jammy-backports main restricted universe multiverse 

二、安装以下常用工具

1. 安装 ssh，ifconfig 等常用网络软件

% sudo apt install net-tools ssh 

2. 安装 gcc 等常用开发库

% sudo apt install build-essential 

三、常用配置命令

1. 添加用户及设置

% useradd [用户名] % sudo vi /etc/group  % sudo vi /etc/sudoers  %sudo ALL=(ALL:ALL) NOPASSWD:ALL [用户名] ALL=(ALL:ALL) NOPASSWD:ALL 

2. 设置远程操作

 % sudo systemctl set-default multi-user.target  % sudo systemctl set-default graphical.target 

2.1 合上笔记本盖子不休眠，取消 #HandleLidSwitch=suspend注释（即删除#号），然后将suspend改为ignore：

% sudo vi /etc/systemd/logind.conf HandleLidSwitch=ignore 

重启服务：

% sudo service systemd-logind restart 

2.2 安装远程 vnc

% sudo apt install vino dconf-editor     

% gsettings set org.gnome.desktop.interface enable-animations false 

3. GPU 显示器安装

Nvidia GPU 安装

% sudo ./NVIDIA-Linux-x86_64-510.85.02.run -z --dkms --no-opengl-files --no-cc-version-check
