After upgrading to Ubuntu 21.10, it seems like multimonitor support is no longer working properly. I can see the options and they're activated, but the RDP session will only use one of the monitors.

Any clues on what I can do to troubleshoot this?

Thanks.

This is because Remmina doesn't fully support Wayland yet. Since 21.04 Ubuntu uses Wayland as the default display server protocol. You can switch to Xorg mode when logging on to the desktop and Remmina will work as good as before.

You can change the display server on the Ubuntu login screen. If your desktop is configured to auto login you have to log out and then log in again.
