+Subject: [PATCH] display: Ensure ::x11-display-opened is emitted at a time
+ there are handlers
+
+During display initialization, the MetaX11Display would be opened at a time
+when we didn't initialize yet the compositor/plugin. The plugin is certainly
+interested in ::x11-display-opened happening, so make sure the signal
+happens late enough that the upper layers are able to connect to the signal
+in advance.
+
+Fixes xsettings/ibus-x11 initialization on the still default "initialize
+Xwayland on startup" wayland compositor behavior.
