Hello, I am using 64 bit F15 with gnome in fallback mode with compiz.
I see the clock in the login screen, but with no changes clock does not show anymore and i can't see the notification area (the four desktops in the right corner as well as the windows name).
I have deleted .gconf and .gconfd (that solved a similar issue time ago), but it does not work this time.
I have tried http://forums.fedoraforum.org/showthread.php?t=265469
but alt+right click does nothing.
