Must use cli-magic to edit unnecessary "whitelist" for Notification Area

This affects Clementine, which by default hides itself in the system tray when the user closes the window. In Unity, once Clementine is hidden there is no obvious way to get it back (even starting the application again doesn't work), and users will think Clementine is crashing or not working.

I suspect there are other third party apps with the same behaviour.

If you want to avoid digging into CLI, you can use dconf-editor to edit the key.

BTW, should we add this setting to unity-preferences? We sure can't add it to CCSM as it isn't a gconf key.

Clementine now supports sound menu, this bug does not affect it. IIRC systray is there temporarily and maybe even be removed in the upcoming release(s). The command below is what we offer.

$ gsettings set com.canonical.Unity.Panel systray-whitelist "['all']"

+Omar:

That is a non-trivial decision (removing systray). What will replace it and will programmers need to alter their code to function with it and will it be configurable by the user and will that config interface be as obtuse and obfuscated as the cli command currently on offer? Don't think I'm afraid of the cli, either. There are many things, like package and file management, that are easier there.

Frankly, I gave Unity a whole release cycle to see if I could live with it. It turns out I can't, and it's largely because of config options. GUI settings should be easily configurable in the GUI. If a thing is intended to be non-mutable, then don't even allow change via cli. I have switched to e17, though fvwm is tempting me back.

Oh, and I filed the bug because it affected (as of Oneiric):
cryptkeeper,
skype,
guake,
pidgin,
wget,
uget,
gnome-globalmenu,
and a handful of other useful widgets and programs that I find useful on occasion.

Its been almost two years since Ubuntu announced they will be depreciating systray and that the developers should port their apps to application indicator, see http://design.canonical.com/2010/04/notification-area/

You seriously can't expect all third-party developers to make code changes to work with whatever notification system each individual distribution comes up with. This is what we have standards for: http://standards.freedesktop.org/systemtray-spec/systemtray-spec-latest.html .
