Any package that previously depended on it now relies on systemd-logind instead. That means that the system must be booted with systemd to be fully functional. In addition to GNOME, both KDE and XFCE are also affected by this change. URL: https://www.archlinux.org/news/consolekit-replaced-by-logind/
