Ubuntu 18.04 LTS was released recently and I quickly installed and began doing some testing. and the steps below is how I disable and enable desktop notifications.
Ubuntu notifications are there to get your attention, notify you of events and display popup messages at the top of your screen. When you get a new chat message or email you will get a notification informing you.
Simply close a notification without selecting it to dismiss it from your screen. These messages will minimize to the system tray for quick access when you need them. The message tray gives you quick access to your notification when it’s convenient for you.
When you click the clock on the top menu or press Superkey + M on your keyboard, the message tray will become available again with all your notifications.
