Currently I can state that in terminal session aka `multi-user.target` (`systemctl isolate multi-user.target`) all variables from */etc/systemd/logind.conf* are sourced normally. So the problem is with GNOME session (`systemctl isolate graphical.target`) in `gnome-settings-daemon` or something other.
