TBH, it sounds like an Xorg problem. Sure, it might be triggered by a
slightly different DBus behavior on the systemd side, but that doesn't
necessarily mean it's a bug in systemd. I have no idea why your
Xserver loops, I don't know the codebase very well.

It looks like your xserver never dispatches the DBus FD, but I cannot
tell you why.
