Inspect output of systemd-cgls.It seems neither su nor sudo add process to the user context (proper cgroup, XDG session), so attempts to talk to the systemd user session through D-Bus fail.

To my surprise, it does not work if I set BUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus" instead of XDG_RUNTIME_DIR. I expected that the former is required for systemd-run.
This command works from a root shell prompt, I hope it should work during resume as well.
