DW Blackjack – Disabling Wayland on Linux Servers
-----------------------------------
Related Products: DW Blackjack Servers (Ubuntu/Linux)
Affected Roles: Administrator, Power User

Overview
Wayland is a modern display server protocol implemented on many Linux/Unix-like distributions as a replacement for Xorg (X11).
Digital Watchdog Technical Support may require TeamViewer remote access to a server to assist with troubleshooting. In some environments, TeamViewer’s interactions with the Wayland display protocol prevent remote access from being established. Disabling Wayland and reverting to Xorg (X11) resolves this compatibility issue.
Supported/Affected Devices
- DW Blackjack Server Series (Ubuntu/Linux OS)
Disabling Wayland
-
Access Your Server’s Operating System
If you are not logged into the desktop, you may need to enter the server credentials.
Default Login — User: dwuser | Password: Dw5pectrum
-
Open Terminal
Press CTRL + ALT + T to open a Terminal window.
-
Access the Configuration File
Enter the following command, then press ENTER:
sudo nano /etc/gdm3/custom.confWhen prompted, enter the OS password (default: Dw5pectrum), then press ENTER. The password will not be visible as you type.
The configuration file will open. By default it contains the following line:
#WaylandEnable=false
-
Edit the Configuration File
Using the ARROW KEYS, navigate to the line:
#WaylandEnable=falseRemove the # character from the beginning of the line so it reads:
WaylandEnable=false
-
Save the Configuration File
Press CTRL + X to exit the editor.
Press Y to confirm saving the changes.
Press ENTER to write the changes to the file.
- Restart the System
The terminal will return to the command prompt. Type the following, then press ENTER:
sudo reboot
- Verify the Active Display Server
Once the system has fully rebooted, open Terminal again (CTRL + ALT + T). Enter the following command, then press ENTER:
echo $XDG_SESSION_TYPE
The terminal should return x11, confirming that Xorg is now the active display server and TeamViewer access should function normally.
NOTE: If the terminal does not return x11, verify that the # was removed correctly from the WaylandEnable=false line and that the file was saved before restarting.
