I'm running openSUSE 11.2 with KDE 4.4.2.

Since i installed KDE 4.* Whenever I go to shutdown, I get the shutdown dialogue, I hit shutdown, it logs me off, shows some text on shutdown screen, and then opens up the GUI again, bringing up a small window, where It asks for the root password, in order to shutdown. If i don't give it the root password, it goes to the login screen.

I cannot, any way, command line, GUI, or anything, shutdown without providing a root password.

Is this a KDE bug, is there a fix, or should I report this in the opensuse bugzilla/forums?

TIA.

This is definitely not expected behaviour. I would recommend asking in the openSUSE forums regarding this, as it sounds like a lack of group membership or KDM configuration issue...
