Ubuntu – Suspend command in Ubuntu 16.04


In Ubuntu 14.04 I used to use the following command to suspend the computer as a user without root privileges:

dbus-send --system --print-reply --dest="org.freedesktop.UPower" \
/org/freedesktop/UPower org.freedesktop.UPower.Suspend

Unfortunately in Ubuntu 16.04 this doesn't work anymore and I get an error message:

Error org.freedesktop.DBus.Error.UnknownMethod: No such method 'Suspend'

Apparently there has been some changes so what would be the correct command now?

As per Debian's wiki, with systemd this is the new command:

systemctl suspend

NOTE: This command still requires root privileges if there is another user's session open. It also doesn't work in Cron. In both cases you you will need to create extra settings.
