I'm using ubuntu 12.04 with gnome-shell and "mediaplayer-extension" from https://extensions.gnome.org/extension/55/. When i hit the close button on a music player, like rhythmbox 2.9x, it hides somewhere, but it keeps playing music in the background. But if i try to do the same on another distro, when I hit the close button, rhythmbox quits instantly.
The question is: What's the program/app/daemon's name that "plays" music in background even if i try to quit rhythmbox (or any music player without a tray-icon) with "close" button? If i try to remove that program, will rhythmbox (or any music player) quit on "close" button? (because i need that)
I know it isn't "mediaplayer-extension" nor "rhythmbox-client", but i can't identify the program. Can somebody help me? Thanks.
(My native language isn't english so i don't know if it's well drafted.)
For clarification, what I'm wondering is:
Why does rhythmbox hide on Ubuntu by hitting on "close" button instead of quitting it?
Why does rhythmbox quit on Fedora by hitting on "close" button instead of hiding it?
Is there a program that modifies rhythmbox's behaviour in ubuntu that fedora doesn't have, or viceversa?
It doesn't only happen in rhythmbox. If i use another music player, like quodlibet or banshee (both without tray icon), it keeps playing music on Ubuntu, but quits instantly on Fedora when i hit on the same "close" button.
Is that (hide-on-close) a normal behaviour that i can only find on Ubuntu?
