Disable Gnome 3 notifications/pop-ups/integrated notifications

Question

If you have Gnome 3.2, you simply click on your user menu at the top-right and flip the Notifications switch.

On Gnome 3.28.4: At top-right corner of screen: Settings > Notifications > Flip the switch:

From CLI:

gsettings set org.gnome.desktop.notifications show-banners false

I was frustrated about this too.

Install dconf-editor, run it, and go to

org.gnome.empathy.notifications

and disable the first three options (signin, signout, away).
