Persistent notifications in Unity

Solution 1:

I read an article about this quite a while ago, so I don't know if it's working at this moment. The package is called "Recent Notifications" and can be found at: https://launchpad.net/~jconti/+archive/recent-notifications

The original article where I read about it:

http://www.omgubuntu.co.uk/2012/03/how-to-never-miss-an-ubuntu-notification-again

How to install via the terminal:

sudo add-apt-repository ppa:jconti/recent-notifications
sudo apt-get update
sudo apt-get install indicator-notifications
