Cannot connect to x-server after switching to WSL2.0 Unable to init server: Could not connect: Connection refused

Before installing vcxsrv-64.1.20.9.0.installer.exe,

After starting the x-launch server

Cannot open display window via bash

error:

Unable to init server: Could not connect: Connection refused
(gedit:2705): Gtk-WARNING **: 17:54:46.065: cannot open display: :0.0

The reason may be that after WSl2.0 is changed, it is unable to connect to the server

Need to change ~/.bashrc file

sudo vim ~/.bashrc

#输入下面一行，下面为windows系统IP地址
export DISPLAY=192.168.0.103:0

#退出后 输入bash命令 生效
source ~/.bashrc

Then open the x launch server side

Pay attention to cancel access control! ! !

Click next, then finish.

Try to open again, such as gedit ~/.bashrc

Successfully opened the window!
