-++++Old| For 18.04 I decided to go with TigerVNC according to Linuxize [[https://linuxize.com/post/how-to-install-and-configure-vnc-on-ubuntu-18-04/|How to Install and Configure VNC on Ubuntu 18.04]]. The main difference is that I can not be bothered using a secure link in my home private network. So to allow a direct connection add ''-localhost no'' to the TigerVNC command line to allow direct connection, see GitHub TigerVNC notes unable to connect to socket: [[https://github.com/TigerVNC/tigervnc/issues/117|Connection refused(10061) #117]]+I want a simple server GUI VNC system.  Sadly most the instructions on the net do not seem to meet my needs. 
 +  * Install a GUI 
 +    * A light desktop system, e.g. xfce 
 +    * The x11 windows manager system 
 +    * A display manager, optional 
 +    * ''sudo apt install --no-install-recommends xfce4 xserver-xorg'', xfce-goodies is an option package 
 +After setting up a basic Debian server I do the following. 
 + 
 +Some additional confusing notes: 
 +  * ''vncserver -list'' on server to check running server sessions 
 +  * ''vncserver -kill :1'' to kill the :1 server listed 
 +  * ''vncserver -localhost no -geometry 800x600 -depth 24'', use the ''-localhost no'' option to allow remote connection. 
 + 
 +I had a lot of problems getting tigervncserver to work with xfce.  The site [[https://unix.stackexchange.com/questions/762533/tigervnc-xfce-startup-failing-on-new-debian-12-bookworm-install-another-sessio|TigerVNC Xfce startup failing on new Debian 12 bookworm install. "Another session manager is already running"]] 
 +This recommended the following ''~.vnc/xstartup'' configuration that simply worked, it took a long time to find a solution: 
 +<code>#!/bin/bash 
 +[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup 
 +[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources 
 +vncconfig -iconic & 
 +dbus-launch --exit-with-session xfce4-session</code> 
 + 
 +The parameter ''vncconfig -iconic'' is for X clipboard support. 
 + 
 +My ''~./vnc/config'': 
 +<code share>session=xfce 
 +geometry=2000x1200 
 +localhost=false</code> 
 + 
 +The ''localhost=false'' parameter means that you do not need ssh to access.  As this is on my LAN only I do not see the need for SSH.  (If i need WAN access I can Wireguard VPN into my local LAN.) 
 + 
 +When I finally got tigervncserver with xfce on Debian 12 the XFCE session came up with an annoying authorisation request that I found a resolution at [[https://www.geekdecoder.com/how-to-fix-authentication-is-required-to-create-a-color-profile-managed-device-on-ubuntu-22-04/|How to fix “Authentication is required to create a color profile/managed device”]] 
 + 
 + 
 +  * sudo systemctl status tigervncserver@:1.service 
 +  * sudo systemctl start: tigervncserver@:1.service
