+The login sound uses the GTK sound theme. Configure this using GTK configuration files or gsettings. Replace "name" with the name of the theme you want to use.
+Note that if you enable all sound events as shown below, you'll also hear GTK sounds when moving around menus, buttons, etc, if the sound theme has sounds for those events.
+To configure the theme name with gsettings, do as follows.
+    gsettings set org.gnome.desktop.sound theme-name name
+If you'd like all sound types enabled:
+    gsettings set org.gnome.desktop.sound input-feedback-sounds true
+    gsettings set org.gnome.desktop.sound event-sounds true
+To configure with a config file, the file is ~/.config/gtk-3.0/settings.ini
+```ini
+[Settings]
+gtk-enable-event-sounds=1
+gtk-enable-input-feedback-sounds=1
+gtk-sound-theme-name=name
+gtk-modules=canberra-gtk-module
+```
