How to start IBus

Hi, I have a new installation of Fed 18. I need IBus for Chinese input. It is installed, but I can't start it. I need IBus to start on boot.

Package ibus-1.5.1-2.fc18.x86_64 already installed and latest version
Nothing to do
[peter@localhost ~]$ ibus restart
Can't connect to IBus.
[peter@localhost ~]$ sudo ibus restart
Can't connect to IBus.
[peter@localhost ~]$

Any tips out there??
