GNOME is removing the legacy system tray: https://bugzilla.gnome.org/show_bug.cgi?id=785956

Appindicator is supported by the extension: https://extensions.gnome.org/extension/615/appindicator-support/ , which is installed default on Ubuntu's GNOME.

Currently, to enable AppIndicator support on GNOME, it's necessary to add the following to electron .desktop files: Exec=env XDG_CURRENT_DESKTOP=Unity /usr/bin/app

• Electron version: 1.7.8
• Operating system: Linux

Expected behavior

AppIndicator icons should be displayed on GNOME using the AppIndicator extension.

Actual behavior

Electron apps use the legacy tray by default on GNOME, which is no longer supported.

How to reproduce

Launch an electron app that creates a system tray icon on GNOME.
