- Date: Fri, 6 Nov 2009 18:30:37 +0000 (UTC)
commit d2d90570c4da0ba7c7f63539c1098e5ac5f6ee4f
Author: Bastien Nocera <hadess hadess net>
Date: Tue Oct 27 23:33:46 2009 +0000
Use gnome-settings-daemon popup code
Instead of forking it.
Also make sure the location of the popup matches
that used by gnome-settings-daemon, and we switch
styles when switching compositing on/off.
