New mail notification changed to a blue string in the upper left corner

Question

After recent update my new mail notification is changed to a very simple blue line in the upper left corner of the screen. Any ideas how can I change it back to a normal Unity notification? I'm on Ubuntu 14.04 with Unity.

Solved! Thanks to this: Notify-osd notifications appear unthemed in top-left corner

It turned out that the problem appeared after I played around with the i3 windows manager. I didn't like it so I purged it. But some packages remained and dunst was the culprit!

I executed sudo apt-get purge dunst and then also sudo apt-get purge i3 i3-wm i3lock suckless-tools i3status.
