Remote Screen Blank in Ubuntu 22.04 | Switch Wayland to Xorg

scottalanmiller

If you update to a recent version of Ubuntu, especially Ubuntu 22.04 you will likely have remote access tools like MeshCentral, RDP, Remote Desktop, ScreenConnect, ConnectWise, LogMeIn, and others stop working.

This is generally because Ubuntu has switched from using Xorg by default to using Wayland and changes which is used during the upgrade process. Normally all we have to do is change it back.

vi /etc/gdm3/custom.conf

Edit this file and Ubuntu has handily included a commented out line for us:

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

Just remove the comment mark, the pound sign (hashtag for the youngsters), save and reboot. Voila.

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

Correct me if I'm wrong, but didn't the previous version allow you to switch window managers at the login? I seem to remember that from a year or two ago.

You can do so ONLY if you have access to that screen. If you are using remote access, you can't get to the point of choosing.

That is not fixing the problem though. Simply working around it.

The problem is why do these tools not work under Wayland?
