Because of some reasons, some indicators had corrupted in AWN... for example, nm-applet, gnome-power-manager...etc.
so I've tried to revive the previous env such as gtk2...
then I could do that.
the point is that power-management tool of gnome3 had been changed dramatically. so I had to employ battery applet of AWN. but nightmare had not ended yet.. XD

and then nm-applet also had shifted to systray.
today we're under the situation of "gtk2/gtk3 composited". so gtk theming is quite hard to fit within them each other... X(
