centos 9 tigervnc met Oh no! Something has gone wrong.

I tried to login vnc of centos9, the server was started by 

vncserver

I got "Oh no! Something has gone wrong."

I found "vncserver has been replaced by a systemd unit and is now considered deprecated and removed in upstream. " in .vnc/test:1.log, I searched by bing, found the right way to config vnc at 

https://www.server-world.info/en/note?os=CentOS_Stream_9&p=desktop&f=2

I edit /etc/tigervnc/vncserver.users, and added ":1=lufei", then start vncserver by "systemctl enable --now vncserver@:1", finally worked fine.
