So you literally CANNOT log in remotely :) If you are lucky, you can assist remotely to a session someone opened locally on that machine.
And it's like that on any other WM. KDE also has a deceiving option in settings that suggests full remote desktop, while it doesn't allow that.
> GNOME Remote Desktop supports integrating with the GNOME Display Manager (GDM) to achieve remote login functionality. This feature is only available via the RDP protocol. It works by the remote user first authenticating via a system wide password, which gives access to the graphical login screen, where they can login using their user specific credentials.
And then it seems to describe a pure-cli config process that you could set up once over SSH and then be able to RDP to the box thereafter.
Actually for that matter, the next section - https://gitlab.gnome.org/GNOME/gnome-remote-desktop#headless... - appears to describe doing a single-user version of the same, explicitly running headless.
Please do.
I've seen too many threads like this based on a hunch and docs, while it just doesn't work.
I'll be more than happy to be proven wrong.
I use it very regularly. Particularly the headless part (where nobody is logged in physically, just a remote session).
