How To Enable Screen Sharing in Ubuntu 18.04 with Vino

Ubuntu 14

In this tutorial, we will walk through the process of enabling screen sharing on Ubuntu 18.04 with Vino. Vino is a VNC server for GNOME, which allows you to share your desktop with other users over a network.

Quick Answer

To enable screen sharing in Ubuntu 18.04 with Vino, you need to log in with Xorg, open the Settings application, navigate to the Sharing section, and enable the Screen Sharing option. If you do not see the option, you can try installing the dconf-tools package or the vino package.

Prerequisites

Before we start, ensure that you have administrative access to the Ubuntu 18.04 system and that it is updated to the latest version.

Step 1: Log in with Xorg

The first step towards enabling screen sharing in Ubuntu 18.04 is to log in using Xorg. Here’s how:

  1. Log out of your current session.
  2. Click on your username to start the login process.
  3. Before entering your password, click on the gear icon next to the password field.
  4. From the dropdown menu, select the Ubuntu with Xorg option instead of the default Ubuntu option.
  5. Log in to your account.

If you do not see the “Ubuntu with Xorg” option, it may be because you are using a different display server called Wayland. In that case, refer to the solutions provided later in this guide.

Step 2: Enable Screen Sharing

Once logged in with Xorg, you can enable screen sharing by following these steps:

  1. Open the Settings application.
  2. Navigate to the Sharing section.
  3. You should now see the Screen Sharing option available.
  4. Enable the Screen Sharing option to start sharing your screen.

If you still do not see the Screen Sharing option, you may need to install the dconf-tools package or the vino package. The following sections provide detailed steps on how to do this.

Solution 1: Install dconf-tools and Disable Encryption

  1. Open a terminal. You can do this by pressing Ctrl + Alt + T.
  2. Run the following command to install the dconf-tools package:
sudo apt-get install dconf-tools
  1. After the installation is complete, disable encryption for remote access by running:
dconf write /org/gnome/desktop/remote-access/require-encryption false
  1. Start the Vino server:
/usr/lib/vino/vino-server --sm-disable start
  1. Go back to the Settings application and navigate to the Sharing section. The Screen Sharing option should now be available for you to enable.

Solution 2: Install Vino

If the first solution does not work, you can try installing the vino package.

  1. Open a terminal.
  2. Run the following command to install the vino package:
sudo apt-get install vino
  1. After the installation is complete, open the Sharing settings directly by running:
gnome-control-center sharing
  1. Enable the Screen Sharing option from the settings window.

This guide has provided detailed steps on how to enable screen sharing on Ubuntu 18.04 with Vino. If none of the solutions work, there may be other factors or configurations affecting the availability of the screen sharing option.
