What you describe, is exactly my situation. I'll try a bit that way.
Just guessing in the dark, i'm under the impression that *polkit and
dbus are closely depending on another ...

It's to see and to try, if there are losses without dbus. E.g. i know,
that thunar in some conditions needs to be started by dbus-launch to
correctly mount (usb)devices on the fly ...

In any case, i'm very interested in a systemwide solution to halt,
shutdown, restart, suspend the system. I thought it could be done by an
append to sudoers (i followed the arch linux instruction, but it seem
to *NOT* work). Your line does it?

As for the login-manager it should be possible to integrate it (at
least i think in lxdm that can be done?).

Cheers.
