Gnome Shell: No tray icon

[sebadorn]

I upgraded today from Ubuntu 14.04.4 to 16.04.1. After that Quod Libet's tray icon wasn't visible, but still interactable. Only the tray icon is affected, all other icons (application menu etc.) show just fine.

Some general info:
Quod Libet 3.6.2, Gnome Shell 3.18.5 with TopIcons extensions, Numix icon theme (but changing the icon theme didn't solve the problem).

---

After some digging, I found that quodlibet.app.symbolic_icon_name() in quodlibet.appindicator returned "None-symbolic", because quodlibet.app.id is not set (same with quodlibet.app.name). So I changed the ID to 'quodlibet'.

Still didn't show the icon. So I probably have to add a "quodlibet-symbolic" icon to the theme, but I just changed symbolic_icon_name() to omit the "-symbolic" part and now it works:

---

Btw: I love how fast indexing and searching are in Quod Libet and the tagging + renaming options of Ex Falso. Great job!

hm, could it be that only the "exfalso" package is up to date, but not the "quodlibet" package?

[sebadorn]

If it is relevant: I use the PPA http://ppa.launchpad.net/lazka/ppa/ubuntu to keep Quod Libet up-to-date.

[lazka]

ok. another weird thing is that appindicator should only be used when running under unity, not gnome.

I'll try installing gnome under 16.04

[lazka]

Are you using lightdm (ubuntu login screen) or gdm3 (gnome login screen)?

[sebadorn]

lightdm.

quodlibet.util.is_unity() returns True for me. Maybe because I also have Unity installed, though I'm using Gnome Shell?

[lazka]

It detects if unity is running not if it's installed.

Do you use default ubuntu or gnome ubuntu etc..?

[sebadorn]

The "normal" Ubuntu. I think since 12.04 I only used upgrades, never a fresh install. At some point I installed gnome-shell.

[lazka]

I can't reproduce with an updated 16.04 + gnome + lightdm. No idea how else we can detect if unity is running. Maybe check for "com.canonical.Unity.Launcher" as well?

And the unset app.id is a different problem which I don't know how it can happen (It gets set in /usr/bin/quodlibet)

[sebadorn]

Oh, my mistake, sorry. app.id is set. It wasn't because I did my testing in a Python console and just did an import quodlibet. When properly starting /usr/bin/quodlibet it is set.

I changed my workaround now to have is_unity() check for com.canonical.Unity.Launcher which returns False in my case and added the "-symbolic" back in. The tray icon is still working.

Checking for com.canonical.Unity returns True, but com.canonical.Unity.Launcher returns False. Here is my (shortened) result for bus.list_names():

Thanks for debugging.

Regarding the icon: We don't want to use the indicator anyway under GNOME, so it doesn't matter if it is broken there. Also gnome has no official app indicator implementation, there is just this unmaintained extension: https://extensions.gnome.org/extension/615/appindicator-support/

Will be available in the next release or in the unstable PPA right now.
