VNC on debian 11 can't get it working on fress install

Hello all,

I am struggling getting VNC to behave on a fresh install.

I followed these instructions:

https://computingforgeeks.com/install-and-configure-tigervnc-vnc-server-on-debian/

~~~~~ This command works and brings up a vnc server I can log into:

vncserver -xstartup startxfce4 &

~~~~~ Here is the start of the logfile of a successful start:

mark@debian:~/.vnc$ cat debian\:5901.log

Xvnc TigerVNC 1.11.0 - built 2022-01-26 17:59

Session startup via '/home/mark/.vnc/xstartup' cleanly exited too early (< 3 seconds)!

Maybe try something simple first, e.g.,

tigervncserver -xstartup /usr/bin/xterm

The X session cleanly exited!
