According to Phoronix , a recently merged PR for the GNOME desktop environment implements important parts of Remote Desktop Protocol (RDP) support.
As stated in the PR, this feature is used to provide graphical remote login support. The PR has been open since August 2022 and was not merged until January 2024. Implementation of this feature relies on changes in GNOME Session, GDM, and the GNOME Settings Daemon, which have been merged over the past year. This means that this feature will be officially launched in the GNOME 46 version released in March.
The specific implementation details of this feature include the abstraction of the standard daemon process and the implementation of two new behaviors. The first is run as a system service, which requests GDM to start a headerless GDM login session on a new RDP connection. The second is to run in a headerless user session (aka daemon-handover), which tells the system service to use the handover dbus interface to initiate the handover process. The implementation of these two behaviors allows the GNOME desktop environment to handle the needs of graphical remote login.
In addition, this feature also supports Wayland. This means it will not only run on X11, but also on Wayland. This is good news for users because they can use this feature on different display servers.
