User name on top-right most tray vanished! I can't see it any more. I see the power button and directly beside it is the clock, I'm using Ubuntu the latest version until now (v.12) 32-bit Any solutions to get it back showing??
From your dash unity search for dconf-tools
under apps-->indicator-session check user-show-menu as shown below in the pic
Or you can use Ubuntu-tweak
To install if you don't have yet:
Using Version 0.7.3
Then go to Tweaks menu and choose Session Indicator and then under User Indicator you can Turn it Off
