I know how to whitelist applications so as to allow them into the Unity system tray, but how do I figure out exactly what string I need to whitelist?

The application I'm interested in is cdemu-tray, but a general answer would be nice.

  • Enable the system tray icon in your applications
  • Run unity from a gnome-terminal

You will see something like this in the output:

** (compiz:3932): DEBUG: TrayChild Rejected: Opera opera Opera

I'm not exactly sure why it's those three in this case, but just adding opera or Opera to the whitelist works. If you start Unity again, you'll get:

** (compiz:4034): DEBUG: TrayChild Accepted: Opera opera Opera
