WSL2 下的tigervnc 配置和正常虚拟机下的略有不同。需要调整一下色深的设定来避免部分Desktop Environment 颜色的问题。

1. 下载最新的tigervnc 版本 （1.5.0 开始支持鼠标前后键的返回和前进）并安装Release TigerVNC 1.15.0 · TigerVNC/tigervnc
2. 按照ArchWiki的2.1走:For a quick start, see the steps below. Users are encouraged to read vncserver(8) for the complete list of configuration options.
   1. Create a password using vncpasswd which will store the hashed password in $XDG_CONFIG_HOME/tigervnc/passwd. Ensure the file’s permission is set to 0600. If creating vncserver access for another user, you must be logged in as that user before running vncpasswd.
   2. Edit /etc/tigervnc/vncserver.users to define user mappings. Each user defined in this file will have a corresponding port on which its session will run. The number in the file corresponds to a TCP port. By default, :1 is TCP port 5901 (5900+1). If another parallel server is needed, a second instance can then run on the next highest, free port, i.e 5902 (5900+2).
   3. Create $XDG_CONFIG_HOME/tigervnc/config and at a minimum, define the type of session desired with a line like session=foo where foo corresponds to whichever desktop environment is to run. One can see which desktop environments are available on the system by seeing their corresponding .desktop files within /usr/share/xsessions/. For example:

   session=lxqt
   geometry=1920x1080
   localhost
   alwaysshared

   我自己的配置

   session=gnome
   geometry=1920x1080
   depth=32
   localhost
   alwaysshared

3. 注册systemd服务 sudo cp /usr/lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@.service
4. 配置自动启动sudo systemctl enable vncserver@:1.service
5. 验证下vncserver是否正确启动sudo lsof -i 。如果没有修改的话，看到590x 即成功。
6. 关闭WSLg。在windows下 %USERPROFILE$\.wslconfig，添加如下的行：

   [wsl2]
   guiApplications=false
