After a Ubuntu Update, I am now missing the gear icon in the top right corner. The right two-most icons are "sound" and "Time and Date Settings".
Ubuntu is running in VMware on Windows 7 Home.
Note; Prior to this update I tried an upgrade to 14.04, but the message said that my laptop would result in poorer performance, so I declined.
Note: Prior to the Ubuntu update, I updated VMware and installed the latest VMware toolbox.
I did find this, but not sure whether it works or how safe it is:
sudo add-apt-repository ppa:jconti/gnome3
sudo apt-get update
sudo apt-get install indicator-applet-complete
