Volume And Battery Icon Missing In Lucid
I had removed "Envelop" from panel in Karmic. After upgrading to Lucid, my volume and battery icons were no where to be seen. Turns out there are indicator-message, indicator-sound, indicator-application and indicator applet which hosts various programs. Indicator message is responsible for hosting Empathy, Pidgin and Evolution. I don't need this. Indicator Sound is responsible for volume icon. I do need this back. So the solution was to remove indicator-message. (Only if you don't want the 'Envelop') sudo aptitude remove indicator-message Be careful that you remove only indicator-message. Now right click your panel and click add to panel. Search for Indicator Applet and add it.
