notify-send not working on Debian Wheezy

Question

I have libnotify-bin installed, yet when I type

notify-send "hello"

nothing happens. No error, no message I have the necessary packages:

# dpkg -l | grep notify
ii  libnotify-bin
ii  libnotify4:amd64

what could be the problem?

I am using LXDE on Debian Wheezy

UPDATE:

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 ?

Solution

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.

@don_crissti - yes, the other machine has the same setup: Debian Wheezy + LXDE

OK, I did not have notification-daemon installed. When I install it and start, then notifications work. It is strange, however. On my other machine the notifications work without notification-daemon. I thought it is using dbus.

I currently have no machine with LXDE running anymore, not sure if it was using DBUS or not.
