Gnome关机按扭不能关机问题解决

我装的是Gentoo.在控制台和GDM登录界面都可以正常关机，但是用Gnome却can't shutdown和reboot.
Google下，在网址
发现yihang1207同学的解决办法是：

控制台以root输入：rc-update add consolekit default

And another article:


Woohoo! Fixed it.
It was resolved in this buggreport:

Only thing I needed was to add this into /etc/dbus-1/system.d/ConsoleKit.conf.

....
send_member="GetSessionsForUser"/>
send_member="GetSystemIdleHint"/>
send_member="GetSystemIdleSinceHint"/>
send_member="GetSessions"/>

send_member="GetId"/>
....

Thanks for all the help!
Gentoo ftw
