System tray icons no longer available in *GNOME Shell*
The system tray icons that showed on the top of the screen are no longer available in *GNOME Shell* version 3.26 in Red Hat Enterprise Linux. As a workaround, you can install the *TopIcons Plus* extension for *GNOME Shell* which moves status icons to the top bar.
Description of problem:
Applications like SpiderOakGroup (backup utility), synergy (sofware KVM switch), etc still utilize system tray icon that was removed in gnome 3.23 and included in RHEL 7.5
Version-Release number of selected component (if applicable):
RHEL 7.5 Beta
gnome-shell-3.26.2-4.el7.x86_64
How reproducible:
VERY
Steps to Reproduce:
Using synergy from
1. From Fresh RHEL 7.5 HTB GNOME desktop start synergy.
Note: I am doing via ssh, as that remote system has installed aleady
$ ssh -X host1 "synergy --client -f"
-or spider oak-
$ ssh -X host2 "/usr/bin/SpiderOakGroups"
2. Wait
Actual results:
$ ssh -X bock "synergy --client -f"
"sni-qt/23671" WARN 07:28:46.710 void StatusNotifierItemFactory::connectToSnw() Invalid interface to SNW_SERVICE
QMetaObject::connectSlotsByName: No matching signal for on_windowShown()
*** WARNING *** The program 'synergy' uses the Apple Bonjour compatibility layer of Avahi.
*** WARNING *** Please fix your application to use the native API of Avahi!
*** WARNING *** For more information see <http://0pointer.de/blog/projects/avahi-compat.html>
No systemtrayicon available
In addition get pop-up window that states:
System tray is unavailable, don't close your window.
-or-
$ ssh -X t470s "/usr/bin/SpiderOakGroups"
"sni-qt/1977" WARN 07:36:27.388 void StatusNotifierItemFactory::connectToSnw() Invalid interface to SNW_SERVICE
No systemtrayicon available
Expected results:
In RHEL 7.0 - 7.4 these applications work out of the box, users will expect the same when install RHEL 7.5
Work-Around:
Install & Enable: (dbus or gnome-tweak-tool) the gnome-shell-extension-top-icons

Enable top-icons extension in default session
The easiest option to address this is to install and enable the already packaged top-icons extension by default.
gnome-shell-extension-top-icons is now dependency of gnome-classic-session and is enabled by default in Gnome Classic Session.
There is an issue with auto-started applications and systray - see rhbz#1550115 for more details.
