How To Fix TeamViewer Error Message for Remote Access on Ubuntu 22.04

Ubuntu 3

In this guide, we will walk you through the process of fixing the TeamViewer error message for remote access on Ubuntu 22.04. This error typically occurs due to the default windowing system used by Ubuntu, which is Wayland. For TeamViewer to work seamlessly, we need to switch to X11.

Quick Answer

To fix the TeamViewer error message for remote access on Ubuntu 22.04, you need to switch from the default Wayland windowing system to X11. This can be done by editing the /etc/gdm3/custom.conf file and uncommenting the line WaylandEnable=false. After saving the changes and restarting the system, you should be able to connect to your Ubuntu server using TeamViewer without any user interaction at the desktop.

Understanding the Issue

By default, Ubuntu 22.04 uses Wayland as the windowing system. Wayland requires user interaction to accept TeamViewer connections, which can be a problem for remote access. However, TeamViewer works seamlessly with X11, which is why we need to switch from Wayland to X11.

Switching from Wayland to X11

To switch from Wayland to X11, we need to edit a configuration file and restart the system. The steps are as follows:

Open the Terminal

Firstly, open the terminal on your Ubuntu server. You can do this by pressing Ctrl + Alt + T on your keyboard.

Edit the Configuration File

Next, we need to edit the /etc/gdm3/custom.conf file. We can do this using a terminal text editor like vim. Run the following command:

sudo vim /etc/gdm3/custom.conf

In this command, sudo is used to execute the command with root privileges, vim is the text editor we are using, and /etc/gdm3/custom.conf is the path to the configuration file we need to edit.

If you are not comfortable with vim, you can use any other text editor you prefer, such as nano or gedit.

If you don’t have permission to edit this file, you need to give yourself sudo permission for the /etc/gdm3 folder. Run the following command:

sudo chmod a+rwx /etc/gdm3

In this command, chmod is used to change the permissions of files or directories, and a+rwx gives all users read, write, and execute permissions.

Uncomment the Line

In the custom.conf file, locate the line that says:

# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false

Remove the # symbol at the beginning of the line to uncomment it, so it becomes:

WaylandEnable=false

This line of code disables Wayland and forces the login screen to use Xorg, which is compatible with X11.

Save and Exit

Save the changes and exit the text editor. In vim, you can do this by pressing Esc and then typing :wq followed by Enter.

Restart the System

Finally, restart your Ubuntu server for the changes to take effect. You can do this by running the following command:

sudo reboot

In this command, reboot is used to restart the system.

Once your server restarts, you should be able to connect to it using TeamViewer without the need for user interaction at the desktop.

Why am I receiving a TeamViewer error message for remote access on Ubuntu 22.04?

The error message occurs because Ubuntu 22.04 uses Wayland as the default windowing system, which requires user interaction to accept TeamViewer connections. This can be problematic for remote access.

How can I fix the TeamViewer error message?

To fix the error message, you need to switch from Wayland to X11, which is compatible with TeamViewer. This can be done by editing the /etc/gdm3/custom.conf file and uncommenting the line WaylandEnable=false. After making the changes, restart your Ubuntu server for them to take effect.

How do I open the terminal on Ubuntu 22.04?

To open the terminal, you can press Ctrl + Alt + T on your keyboard. This shortcut will launch the terminal on your Ubuntu server.

Can I use a text editor other than vim to edit the configuration file?

Yes, you can use any text editor you prefer, such as nano or gedit. If you are not comfortable with vim, you can replace sudo vim in the command with sudo nano or sudo gedit to open the file with the respective text editor.

Do I need root privileges to edit the configuration file?

Yes, you need root privileges to edit the /etc/gdm3/custom.conf file. That’s why we use sudo before the text editor command (sudo vim /etc/gdm3/custom.conf). It allows you to execute the command with elevated privileges.

What should I do if I don’t have permission to edit the configuration file?

If you don’t have permission to edit the file, you can give yourself sudo permission for the /etc/gdm3 folder by running the command sudo chmod a+rwx /etc/gdm3. This command grants all users read, write, and execute permissions for the folder.
