Created attachment 5463 panel displayed still having clock. After upgrading to LTS 14.04, the network-manager applet was gone. As described here. http://www.ubuntuask.com/q/answers-networkmanager-tray-nm-applet-is-gone-after-upgrade-to-14-04-trusty-449658.html After adding xfce4-indicator-plugin "Indicator Panel" to the panel. I got back a network manager. Quite easy. So I was supposing that was the new way to have my network applet back. But the xfce4-indicator-plugin also display a clock which I already have and also some other unwanted stuff. The configuration seems proposing to edit it, but it do nothing. whitelisting and blacklisting apps. Here's a snipet of .config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml <property name="plugin-14" type="string" value="indicator"> <property name="known-indicators" type="array"> <value type="string" value="libapplication.so"/> <value type="string" value="com.canonical.indicator.power"/> <value type="string" value="com.canonical.indicator.datetime"/> <value type="string" value="com.canonical.indicator.messages"/> <value type="string" value="com.canonical.indicator.bluetooth"/> <value type="string" value="com.canonical.indicator.keyboard"/> <value type="string" value="com.canonical.indicator.sound"/> </property> <property name="mode-whitelist" type="bool" value="true"/> <property name="whitelist" type="array"> <value type="string" value="com.canonical.indicator.power"/> <value type="string" value="libapplication.so"/> <value type="string" value="com.canonical.indicator.sound"/> </property> The properties editor for xfce4-indicator-plugin, works but only when the applet is added at the first time to the panel. After it seems disabled.

Login out, and restarting helps applying whitelisting (filtering apps displayed). I also switched language from French to English to help screenshoting. Back to French, whitelisting still works, but properties edition of the applet still doesnt work. Tested in English too, same thing. Reload necessary and properties not manageable twice, only once.
This is a limitation of the indicator plugin (note the "Please restart the panel for visibility changes to take effect" message under the list of indicators). So, if you (de)select any of the indicators, you need to restart the panel. Logout/login will work but it may be more convenient for you to use: $ xfce4-panel -r
Oh thanks. I missed that note about restarting. And other edition are not subject to restart… I mean add/remove item to the panel. Could it be a restart button instead of a note? I suppose it cant, because the popup is probably a child of the panel… Do you know why the network-manager and those apps (battery, sounds…) are now handled by the indicator?
