The title of this question is really self explanatory. I intend to send synchronous volume notifications in arch(changing volume and showing the progress bar) and was wondering if I can do this with plain notify-send and xfce4-notifyd(eg. a hint or something).
EDIT1: More precisely I want new volume notifications to replace old ones so that it emulates a volume meter and it doesn't flood my screen.
If not, is this possible with notify-osd or do I need to actually use libnotify?
