This is the top right corner of my screen, where my Gnome Panel displays notification icons. I am using Flashback or Fallback or Classic or whatever it's called right now.
It is missing the Dropbox and sound icons. Also, although I switch between Japanese (Anthy) and US English input, the "En" icon does not change. These problems emerged after upgrading to 15.04.
I have tried running sudo apt-get install libappindicator1
, I have tried deleting all indicator areas and reinstalling them. Nothing has changed.
How do I get Dropbox and sound icons back in my Gnome Panel?
