I have installed notify-send on my Pi but no notifications are appearing. Can anyone suggest how I can find out why not?
The install was 'sudo apt-get install libnotify-bin' and there were no errors reported.
To test it I've tried 'notify-send "Test Message" '. Nothing happens after I press Enter.
In case it didn't know where to send the notification, I entered 'export DISPLAY=:0.0' and tried again.
I've looked in /var/log for error messages, in syslog, messages, daemon.log and lightdm/lightdm.log. Nothing logged.
I'm using Raspbian Jessie.
Any hints or help will be appreciated.
