Live Screenshot Not Working on Ubuntu

Symptom

When you try to take a Live Screenshot in Rise Vision for a Display running Ubuntu, the screenshot is blank or fails to capture.

Why This Happens

This happens because Ubuntu uses the Wayland display server by default. Wayland blocks applications like Rise Vision from capturing the desktop or Display window.

Resolution

1. Open a terminal window on your Ubuntu device.
2. Run the following command to edit the GDM configuration file with administrator privileges:
   sudo nano /etc/gdm3/custom.conf
3. Find the line that says #WaylandEnable=false and remove the # so it reads:
   WaylandEnable=false
4. Press Ctrl + O to save the file, then Enter to confirm, and Ctrl + X to exit.
5. Restart your system using:
   sudo systemctl restart gdm3 or simply reboot your computer.
6. After restart, confirm that Ubuntu is using X11 instead of Wayland by opening a terminal and running:
   echo $XDG_SESSION_TYPE
   If it shows x11, the change was successful.
7. Try taking a Live Screenshot again in Rise Vision.
