Did it ever worked directly on the machine? If not - try other ways to suspend.

I'm not shure you must not use double qoutes for command string, if there are internal field separators in the string:
ssh user-name@host.name "command argument argument"

Yeah machines suspend just fine, I just want to be able to do it remotely. Do you have a command that works?

Yes I have it. This is exact duplicate of mentioned above DBus way command ( http://ubuntuforums.org/showpost.php...7&postcount=57 ).

Code:

---

ssh user-name@host.name "dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Suspend"

---

But you neeed to set up permissions. Into your file
"/usr/share/polkit-1/actions/org.freedesktop.upower.policy"
into section "defaults" you may insert

Code:

---

      <allow_any>yes</allow_any>

---

Ubuntu 12.04 Precise will suspend.

Thank you. I'm still trying to understand this.

Has to be installed on all machines?

Code:

---

sudo apt-get install policykit-1 upower acpi-support

---

There isn't a GUI for policy kit? Instead you edit manually?

Code:

---

sudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy

---

You set policy on receiving or sending machine?

What if it's a Windows machine? For Windows machines on the network, Sysinternals\PsTools\psshutdown.exe works very well but it has to be sent by another windows machine, even a VM.

This is tested on Ubuntu 8.04 (Hardy) with a Dell Inspiron 1520 laptop. I would appreciate feedback from users of other systems.

To suspend-to-RAM (aka sleep):

Code:

---

pmi action suspend

---

To suspend-to-disk (aka hibernate):

Code:

---

pmi action hibernate

---

If you want to lock the Gnome session first (ie. require a password on resumption), then issue the following command before pmi:

Code:

---

gnome-screensaver-command --lock

---

For example, you can use these commands to create a button (launcher) on a Gnome panel (taskbar) that instantly locks the screen and goes into sleep mode:

Right-click panel, Add to panel, Custom application launcher, Add, Name: Sleep , Command: gnome-screensaver-command --lock ; pmi action suspend

---

Good work - you provided a piece of the puzzle for me, and it work's nicely!

I have this in my ~/.bashrc:

Code:

---

# Monitor off and sleep in $1 minutes
off () {
xset dpms force off && echo 'gnome-screensaver-command --lock; sudo pmi action suspend' | at now + $1 minutes
}

---

This switches off the monitor immediately and waits the specified number of minutes before sleeping the system. Great if you listen to stuff before sleeping! e.g. I'm listening to a podcast I know will finish in 47 minutes, so I just issue:

Code:

---

off 50

---

For this to work, I had to edit /etc/sudoers to enable sudo pmi without a password:

Code:

---

$USER ALL=NOPASSWD: /usr/sbin/pmi

---

Thanks again!

I tried the sleep command but I got the error message...

Code:

---

Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files

---

I would love to use this command, but it's not working.

How do I do this on Ubuntu 12.04?

look at post #63

Code:

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