+Subject: [PATCH] util: Unset GNOME_SETUP_DISPLAY at login time
+
+This variable was introduced to allow Xwayland auto-startup.
+Unfortunately, it will prevent g-s-d process startup if it leaks from a
+wayland session to an Xorg session.
+
+As such, add it to the list of variables that are unset at login time.
