VNC_Server_On_Ubuntu_22.04LTS.md

Setup

Install xfce4

sudo apt update
sudo apt install xfce4 xfce4-goodies

Install TigerVNC -

$ sudo apt install tigervnc-standalone-server

Configure VNC Server by running

$ vncserver

This will setup a password to access the server through a remote session.

Create/add this file ~/.vnc/xstartup with the following contents -

#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
startxfce4

Make the file executable -

$ chmod +x ~/.vnc/xstartup

Create a new service file to configure VNC Server to startup as a service on boot -

$ sudo nano /etc/systemd/system/[email protected]

Add the following to the contents of the newly created file -

[Unit]
Description=Start TigerVNC server at startup
After=syslog.target network.target

[Service]
Type=simple
User=someuser
Group=someuser
WorkingDirectory=/home/someuser

PIDFile=/home/someuser/.vnc/%H:590%i.pid
ExecStartPre=-/bin/sh -c "/usr/bin/vncserver -kill :%i > /dev/null 2>&1"
ExecStart=/usr/bin/vncserver -fg -depth 24 -geometry 1920x1080 -localhost no :%i
ExecStop=/usr/bin/vncserver -kill :%i

[Install]
WantedBy=multi-user.target

Update the permissions of the newly created file with

$ sudo chmod +x /etc/systemd/system/[email protected]

Reload the daemons so that it can load the new VNC service -

$ sudo systemctl deamon-reload

Enable the VNC service so that it loads on boot -

sudo systemctl enable [email protected]

Kill any existing VNC servers and start the service -

$ vncserver -kill :*
$ sudo systemctl start vncserver@1

Check the status of the service with -

$ sudo systemctl status vncserver@1

Thanks for this guide :) A little fix, it should be sudo systemctl daemon-reload instead

It should be daemon-reexec actually

If you have issues running graphical apps like Firefox or Chromium, you can allow remote access to X11 from your VNC session by running the following:
xhost +local:

Then run the app as:
sudo dbus-launch firefox

Thanks for the steps

Here I want to use the Queyconnect option but it dosen't work it says failed to open dialog box at local user. Do you have any idea regrading that ?
