I think this is expected, so more of a feature request than a bug. gnome-shell isn't really a Terminal Server like you'd find on Windows. And it's not a remote desktop server like legacy X11. It's primarily a local desktop which can be controlled by remote protocols. But in order to have a desktop to control it needs to have a size, hence a monitor plugged in.
Seems totally reasonable that gnome-shell should support the headless case though. ** Changed in: gnome-shell (Ubuntu) Importance: Undecided => Wishlist ** Changed in: gnome-shell (Ubuntu) Status: New => Triaged ** Bug watch added: gitlab.gnome.org/GNOME/mutter/-/issues #1605 https://gitlab.gnome.org/GNOME/mutter/-/issues/1605 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/2022954 Title: RDP and VNC fail when headless with no monitor (but work otherwise!)
