With dbus 1.8 my system is just fine. 1.10 with systemd prevents a successful X session. More details at https://bbs.archlinux.org/viewtopic.php?id=216001

This appears to be a distro integration issue, or possibly several different distro integration issues with the same user-visible symptom. Please talk to your distro's support channels about this. The maintainers of dbus and whatever desktop environment you are using (XFCE or GNOME or whatever) in a particular distribution are responsible for making sure the versions in that distribution interoperate nicely: this is what distributions do.

Those maintainers will need a lot more information from you, such as which version of which desktop environment you are using, any applicable logs, any non-default configuration files or startup scripts that mention dbus-launch or DBUS_SESSION_BUS_ADDRESS, and so on.

From the linked forum thread, Arch Linux seems to have completely disabled dbus-launch and X11 autolaunching. That's... ambitious, and not something I would do in a general-purpose (non-embedded) distribution this year (quite possibly not this decade either).

I'm the maintainer of dbus in Debian, where dbus-launch and X11 autolaunching are effectively still required. I've started the process of reducing dbus-launch from required to optional by opening over a hundred bugs[1]; many of those bugs need solving upstream before we would even be able to *consider* disabling X11 autolaunching.

Thank you' I've posted your full response back to Arch in the hope that it will result in an ability to upgrade again.
