Step 1: Stop the VNC Server Service

The first step in removing VNC server from Ubuntu is to stop the VNC server service. This is important because if the service is still running, you won’t be able to remove the VNC server packages properly.

To stop the VNC server service, you can use the systemctl command in the terminal. Simply open a terminal window and type the following command:

sudo systemctl stop vncserver-x11-serviced.service

Open Terminal

In order to stop the VNC Server service on Ubuntu, you need to open the terminal. You can do this by pressing Ctrl+Alt+T on your keyboard. Alternatively, you can search for “terminal” in the Activities search bar and open it from there.

The terminal is a powerful tool that allows you to interact with the Ubuntu operating system using text commands. It’s essential for running administrative tasks like stopping the VNC Server service.

Once you have the terminal open, you’re ready to move on to the next step.

Step 2: Remove VNC Server Packages

Check installed VNC server packages: Before removing the VNC server packages, you need to check which packages are installed on your system. This is necessary because Ubuntu may install different VNC server packages based on your needs.

Remove VNC server packages: Once you have identified the VNC server packages installed on your system, you can remove them using the apt-get command. This will remove the VNC server packages and their dependencies.

Remove any remaining packages: After removing the VNC server packages, there may be some remaining packages that were not removed automatically. You can use the apt-get command to remove these packages as well.

Clear out the apt cache: It is a good idea to clear out the apt cache after removing packages. This will free up disk space and ensure that you have the most up-to-date package information.

Verify that VNC server packages have been removed: After completing the removal process, you can verify that the VNC server packages have been successfully removed by attempting to start the VNC server service. If it does not start, then the packages have been successfully removed.

List Installed Packages

Before removing the VNC server packages from your Ubuntu system, you may want to check which packages are currently installed. You can do this using the dpkg command in the terminal. Here’s how:

1. Open the terminal
2. Type the following command and press Enter: dpkg –list | grep vnc
3. You should see a list of packages related to VNC server. Make sure you take note of the exact names of the packages before proceeding with the removal process.

If you don’t see any packages related to VNC server in the list, it means that VNC server is not installed on your system or it has already been removed.

It’s always a good idea to double-check the list of installed packages before proceeding with the removal process to avoid accidentally removing any other important packages that may depend on VNC server.

Uninstall VNC Server Packages

Once you have a list of the VNC Server packages installed on your system, you can proceed to uninstall them using the apt-get command. Open a terminal and run the following command:

• sudo apt-get remove PACKAGE_NAME: This command will remove the specified package and its configuration files.
• sudo apt-get purge PACKAGE_NAME: This command will remove the specified package along with its configuration files and any other dependencies that were installed with it.
• sudo apt-get autoremove: This command will remove any remaining packages that were installed as dependencies but are no longer needed.

Replace PACKAGE_NAME with the name of the package you want to remove. If you have multiple VNC Server packages installed, you will need to run these commands for each package.

Once you have uninstalled all the VNC Server packages, you can proceed to remove any remaining configuration files. Run the following command to remove the VNC Server configuration directory:

• sudo rm -r /etc/vncserver: This command will remove the VNC Server configuration directory.

After removing the VNC Server packages and configuration files, you have successfully removed VNC Server from your Ubuntu system.

Remove Dependencies (Optional)

If you are sure that you no longer need any dependencies related to the VNC server packages, you can remove them. This step is optional, as some dependencies might still be required by other packages on your system.

To remove dependencies, you can use the command:

• sudo apt-get autoremove – This command removes any unused packages, including dependencies that were installed with the VNC server packages.
• sudo apt-get remove package-name – This command removes a specific package and its dependencies.
• sudo apt-get purge package-name – This command removes a specific package and its dependencies, as well as any configuration files associated with the package.

Before running any of these commands, make sure you understand what they do and which packages will be affected. You can also use the apt-cache rdepends package-name command to see which packages depend on the package you want to remove.

Once you have removed the VNC server packages and their dependencies (if desired), you have successfully removed the VNC server from your Ubuntu system.

Step 3: Remove VNC Server Configuration Files

Open Terminal: In Ubuntu, the terminal is used to execute commands. Open the terminal by pressing Ctrl+Alt+T or searching for Terminal in the activities menu.
