      for GTK+-3 or GTK+-2 will be installed.  As the &root; user,
      update a cache file of GTK+-3 or GTK+-2 so the GTK-based applications
      can find the newly installed IM module and use ibus as an input

    <screen role='nodump'><userinput>gtk-query-immodules-3.0 --update-cache</userinput></screen>
