Comment 4 for bug 1473800

This sounds related: http://cgit.freedesktop.org/xorg/xserver/commit/?id=dc48bd653c7e1013e2d69e3f59ae3cbc0c893473 -- Seems current X.org does not like logind to be restarted, but that's what we do right now in the systemd package (so that after a dist-upgrade you actually run the current version).
