+Subject: [PATCH] core: Retrieve DESKTOP_STARTUP_ID early on startup
+
+With the move away from GTK3, and the indirect dependency on GTK4
+grown in the GNOME Shell side, we've indirectly gotten a small sneaky
+behavioral change: The GTK4 library will, right on dlopen, get
+DESKTOP_AUTOSTART_ID for itself and delete it from the environment.
+
+This happens before our own X11 session management code is
+initialized, which confuses the hell out of it, into thinking
+initialization is actually shutdown, gnome-session does not follow
+along with this request, which leaves GNOME Shell into a confused
+startup state where it never calls SmcSaveYourselfDone() and grinds
+startup to a halt until gnome-session decides to move things forward.
+
+In order to fix this, get the DESKTOP_AUTOSTART_ID before we lend
+control to GNOME Shell bits and GTK4 is possibly initialized, and
+feed it directly to our X11 session manager bits.
