[gentoo-user] Can't log into KDE desktop

[Lavender]

Finally, finally I have the Xorg-server worked correctly and installde
KDE Meta. I wanna say it is so difficult to have done these !
Now , I can start KDE, but after I input username and password,
it only showed a panel with four icons( I think you guys who use KDE
will see this everytime when KDE starts), then it did not show the desktop.
Here is my kdm.log:

---- As you can see, it reported that it can't connect to dbus service, so I " /etc/init.d/dbus status"
the result showed that dbus service had started.
I really hope you can help me, I can't wait to see a beautiful KDE desktop :-)
