Eric Valette is being bugged by this issue:
> dbus-send --system --print-reply --dest="org.freedesktop.UPower"
> /org/freedesktop/UPower org.freedesktop.UPower.Suspend
> Error org.freedesktop.DBus.Error.UnknownMethod: Method "Suspend" with
> signature "" on interface "org.freedesktop.UPower" doesn't exist
I ran into this too and as far as I can tell this happens because UPower
has been superseded by Systemd.Logind. So the fix I found is to make the
following call instead:
dbus-send --print-reply --system --dest=org.freedesktop.login1 \
/org/freedesktop/login1 org.freedesktop.login1.Manager.Suspend \
boolean:true
There are similar commands for HybridSleep and Hibernate. The
Systemd.Logind documentation can be found there:
