WSL1-Ubuntu18相关配置，问题解决

一、问题

微软商店安装Ubuntu后，因识别为WSL2报错，在命令行中输入如下命令即可解决：
wsl --set-default-version 1

二、换源

1.备份list文件
进入目录：cd /etc/apt/
备份：sudo cp sources.list sources.list.bak

2.修改list文件：sudo nano sources.list
将里面的内容全部删除，替换为

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

3.更新软件列表：sudo apt update、sudo apt upgrade

三、映射系统文件

依次打开文件资源管理器-此电脑-映射网络驱动器，如图所示：

选择驱动器盘符，在文件夹中输入：
Ubuntu18.04版本：\\wsl$\Ubuntu-18.04
Ubuntu20.04版本：\\wsl$\Ubuntu-20.04

由此打开系统文件

四、配置桌面

1.安装桌面：sudo apt install xfce4 xfce4-terminal gtk2-engines-pixbuf libappstream4
2.下载VcXsrv，打开Xlaunch，选择 “one large window” ，“Display number” 设置为 0，Extra settings中将“Native opengl”的勾去掉，其它选项默认，打开窗口
3.修改配置文件
bash：
echo "export DISPLAY=:0.0" >> ~/.bashrc
source ~/.bashrc
zsh：
echo "export DISPLAY=:0.0" >> ~/.zshrc
source ~/.zshrc
4.运行桌面：startxfce4

运行成功

注：注销WSL-Ubuntu-18.04：命令行输入wsl --unregister Ubuntu-18.04
