I have libnotify-bin installed, yet when I typenotify-send hellonothing happens. No error, no messageI have the necessary packages:# dpkg -l | grep notifyii  libnotify-binii  libnotify4:amd64what could be the problem?I am using LXDE on Debian WheezyUPDATE:While the solution suggested by @Anthon works (install notification-daemon), I am not sure whether that is the best solution. I was expecting that it is enough to have libnotify-bin and libnotify4 and dbus installed. Inedeed, on my other machine, notify-send works without notification-daemon.Can somebody please clarify whether notification-daemon is necessary or not ?
notify-send not working on Debian Wheezy
debian;lxde;libnotify
Your notification daemon has probably not been started. Try to start it by hand with:/usr/lib/notification-daemon/notification-daemon If you have a properly started daemon, you might have hit this bug, which causes the daemon to crash.
