Comment 42 for bug 138691

I have done some more experimenting with "Machine 3" from my previous message. Results:

- If I boot the machine, the press Ctrl-Alt-Del at the login screen (i.e. without logging in) and choose shutdown, the machine *will* shut down properly
- If I boot the machine and log in, then choose "Turn off" via the KDE Menu, the machine will hang as described
- If I remove "quiet splash" from the boot options, the machine *will* shut down properly, even if I do log in. I can still see the Networkmanager/dbus error messages described above during the shutdown process, though.

Given these results, my guess is that X does also play a part in this - rather annoying - bug...
