Setting up a Remote Desktop Connection using RealVNC Server on Ubuntu

When it comes to setting up remote desktop connections, VNC (Virtual Network Computing) is one of the most popular options. In this tutorial, we will show you how to set up a RealVNC server on an Ubuntu machine and connect to it using a VNC viewer.

Starting the VNC Service

To start the VNC service, run the following command: `$ sudo systemctl start`. This will ensure that the VNC service is successfully started. You can verify this by running the following command: `$ sudo systemctl status`.

Enabling the VNC Service

Next, enable the VNC service to start automatically on boot: `$ sudo systemctl enable`. The port on which the VNC service will run is defined by the number 1 after the symbol.

Configuring the VNC Server

To configure the VNC server, you need to create a systemd unit file. Run the following command to do so: `$ sudo vim desktop.service`. Paste the following settings into your text editor and save it:

```

'Unit'

Description=TigerVNC Service

After=network.target

'Service'

User=

ExecStart=/usr/bin/vncserver :1 -geometry 1440x900 -alwaysshared -fg

Restart=always

'Install'

WantedBy=multi-user.target

```

Replace `` with your actual username.

Creating the Xstartup File

To ensure that permissions are right, use the following `chmod` command: `$ chmod u+x ~/.vnc/xstartup`. Create a new file called `~/.vnc/xstartup` and add the following script:

```

#!/bin/sh

xrdb $HOME/.Xresources

xsetroot -solid gray

vncconfig -iconic &

' -x /usr/bin/Composite ' && Composite &

' -x /usr/bin/Xfwm4 ' && Xfwm4 &

```

Save and close the file.

Starting the TigerVNC Server

To start the TigerVNC server, run the following command: `$ vncserver :1`. This will start the VNC service on port 5901.

Connecting to the VNC Server

To connect to the VNC server using a VNC viewer, enter the hostname and password. The hostname is the name of your Ubuntu machine, and the password can be set up during the installation process or later using the `vncpasswd` command.

That's it! You should now have a RealVNC server set up on your Ubuntu machine, and you can connect to it using a VNC viewer.
