X11 shutdown -- slow and many error messages
 

I've noticed that after an X11/KDE "End Session" it takes a long time to actually "shutdown" and return to standard terminal prompt.

Also returning to the terminal prompt I get error messages from kwin, akonadi, and other X11/KDE based error messages.

Does anyone know how to speed up the "End Session" process or how to eliminate terminal error messages that are displayed after shutdown?

Can you post some of the error messages so we can see what is happening please? If the screen clears too quickly, have a look in /var/log/Xorg.0.log

The errors I am seeing may just be part of the X shutting down process but perhaps there is a way to supress those errors. Here is a "summary" of the errors (not exact)

QCore Application :: Unexpected Null Receiver
Qobject :: dataupdated
Akondni Server Lost Connection Resource
Kwin Effects Handle Unload
XError Bad Window Invalid Parameter
Klauncher error
Traceback blueman-applet
Akondai Dbus Shutting Down
Akonadi Dbus shut down normally

Is this normal to see in the console after an X11 shutdown. Can I supress them? Should it take 10-15 seconds normally to shutdown X11 (after hitting the "end session" button)?

Thanks
