Notification in watchr

I can't find an answer to a question. I would like to make a notification in watchr via autotest-notification, but I don't understand how to do it? In Watchr Install section talks about libev. And I tried to do this in my Ubuntu10.10 but after start wa开发者_如何学JAVAtchr notification not appear.

you have to install the libnotify-bin library and use the notify-send command in your scripts if you want to have gnome notifications ala MacOS

Sorry. These issues I have been associated with bug on Ubuntu, when some program is running on full screen notify-send don't work.
