How to hide/remove Rhythmbox Now playing pop-up/notification?

Solution 1:

The infamous popup you are referring to is the Ubuntu notification system.

You'll see that with a variety of applications - weather apps, empathy as well as plugging in external devices.

However if you specifically dont like rhythmbox displaying a notification about which song is playing, it is simple enough to disable it.

From the rhythmbox global menu choose Edit-Plugins or Tools > Plugins, scroll down and deselect Notification

N.B. The global menu can be revealed by hovering your mouse at the top of the screen over the top of the panel which is called the menubar.

Just to add to @fossfreedomg's comment: This is how I did it in Ubuntu 14.04 (trusty)

gsettings set org.gnome.rhythmbox.plugins active-plugins "['artsearch', 'audiocd', 'audioscrobbler', 'cd-recorder', 'daap', 'dbus-media-server', 'generic-player', 'ipod', 'iradio', 'mmkeys', 'mpris', 'mtpdevice', 'power-manager']"

You can list your current settings via:

gsettings list-recursively org.gnome.rhythmbox.plugins

Just had this problem myself and glad to find an answer.

On Ubuntu 20.04 I searched for Notifications and got the following...

When you click the RhythmBox choice you'll see a poup that lets you control things more specifically:

I turned off the Notification Popups and it solved the problem.

The note just means that if you look in the notifications area you will still see a notification of the current song that is playing. However, it won't popup on the screen any longer.
