+Subject: [PATCH] main: Register session with GDM on startup
+
+When no monitor is connected, gnome-shell starts but never emits
+`startup-prepared` nor `startup-complete`. As a result, GDM never
+detects that the shell has launched and plymouthd remains running,
+preventing the system from reaching graphical.target.
+
+Ensure that registerSessionWithGDM() is called even when no monitor
+is connected, so GDM can terminate plymouthd and allow the system to
+reach graphical.target properly.
