How can I suspend/hibernate from command line?

  • How can I suspend or hibernate my laptop using command line, without installing additional software?

    For Ubuntu 16.04, see this question: and its answer `systemctl suspend`

    Traditionally ubuntu supported a fairly blunt method of suspend and hibernate. Neither would integrate well with other apps and sometimes not even work on some machines. The new method doesn't require root and notifies all applications listening for power events.

    Systemd Method

    Starting with Ubuntu 16.04, systemctl call must be used (See Suspend command in Ubuntu 16.04)

    systemctl suspend


    systemctl hibernate

    New Method

    See the answer here on this page from Adam Paetznick regarding the use of dbus. Ideally you would create a ~/bin/suspend shortcut/script that makes the use of this action easy.

    For use over ssh, you should modify policykit rules as outlined by Peter V. Mørch

    Old Method

    According to the Ubuntu Forum you can use the following commands:

    pmi action suspend


    pmi action hibernate

    This requires that you install the powermanagement-interface package (not tested).

    sudo apt-get install powermanagement-interface

    I have also found the commands sudo pm-suspend and sudo pm-hibernate to work on my netbook.

    pm-suspend and pm-hibernate works for me and it's easy. Requires sudo but that's OK. (Found pmi idea before but installing a package to use suspend is well bad...)

    added sudo to the description

    Note that you have to `apt-get install powermanagement-interface` to run pmi.

    On 11.10 only pm-* works, also with powermanagament-interface added

    doesn't work with my ubuntu 12.10. after `apt-get install powermanagement-interface`

    `sudo pm-hibernate` is amazing for making SATA drives really hotplug! :)

    `sudo pm-suspend` works well but while waking up after doing so doesn't ask me for password. what should I do.

    none of the above works, even with sudo rights. not the `pm-hibernate`, `pmi action hibernate`, not the `dbus` stuff. I am sad.

    I'm on 16.04 and both `systemctl suspend` and `pm-suspend` work; the difference being that the latter does not first lock the screen and requires `sudo` to run.

  • The gnome-friendly way is to use dbus.

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

    There are two advantages to this command over pm-suspend.

    1. It will lock your screen (upon resume) if you have that option selected in gnome.

    2. It does not require root privilege, so it is easy to add it as a keyboard shortcut, for example.

    As mentioned in the comments exchanging the Suspend in the last line to Hibernate creates a hibernate command:

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

    If the hibernation throws Error org.freedesktop.UPower.GeneralError: not authorized your user might not be allowed to hibernate. Edit or create /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla so it contains the following section: (source)

    [Re-enable hibernate by default]

    This was tested on UbuntuGnome 14.04.

    Note: This is basically the same as qbi's answer, but updated to work for newer versions of Ubuntu as well as including hibernate.

    Your answer really should be first. It's non-root no-packages-to-be-installed gnome way of doing it. Like!

    That's the right answer! :D

    AFAIK there is another advantage: It allows other program to detect that suspend/resume happened and act accordingly (for example an IM to resume a network connection to a server).

    While this is actually the right way to do it (tm), SSH users should take note of :

    To `Hibernate`, you can simply replace the last line with `org.freedesktop.UPower.Hibernate`

    Under 13.10 I get `Error org.freedesktop.UPower.GeneralError: not authorized`

    on my 13.10 it does work. however, the screen is *not* locked upon resume, even though in "Security and Privacy", "Require my password when waking from Suspend" *is* activated.

    This may be gnome friendly but I can still tell (i.e. wifi/ethernet notification and no graphic glitch) it's not the same clean result than when I do it through the Unity GUI or in the case of my laptop through a hardware suspend button.

    Didn't work for me (Gnome 3.12, Ubuntu 14.04). Seems the [UPower.Suspend] interface was removed, according to

    This did work for me under 14.04 Trusty, but just moved to 15.10 Wily and it no longer works.

    firstly, screen locking is not done, and secondly, after each hibernate-resume, the wifi laggs about every other minute. totally unusable for me.

    Please evaluate if this gnome-friendly method is not superceded by 'the new command of systemd' as indicated in (

    This didn't work for me under Gnome+i3wm in 18.04

    If you want your computer to suspend in one hour because you want to go to bed listening to your favorite radio station, open terminal and type:

    sudo bash -c "sleep 1h; pm-suspend"

    and your computer will fall asleep in 1 hour. When you awake, it will have kept your open images and all your stuff.

    You can replace 1h by what you want: h for hours, m for minutes, s for seconds, d for days.

    Good night!


    Si vous voulez juste que votre ordinateur se mette en veille dans une heure parce que vous voulez vous endormir en ecoutant votre radio préférée, ouvrez Terminal et tapez :

    sudo bash -c "sleep 1h; pm-suspend"

    et votre ordinateur s'endormira dans une heure. Quand vous vous réveillerez, il aura conservé en mémoire vos applications ouvertes.

    Vous pouvez remplacer 1h par ce que vous voulez: h pour les heures, m pour les minutes, s pour les secondes, d pour les jours.

    Bonne nuit!


    Si quieres suspender tu computadora en una hora porque quieres ir a dormir escuchando tu estación de radio favorita, tan solo abre el terminal y escribe:

    sudo bash -c "sleep 1h; pm-suspend"

    y tu computadora se quedará dormida en 1 hora. Cuando despiertes, allí habrán quedado abiertas tus imágenes y todas tus cosas.

    Puedes reemplazar 1h por lo que desees: h para horas, m para minutos, s para segundos, d para días.

    ¡Buenas noches!

    That's my use case I'm looking for! AFIK pm-* can be run without superuser permissions

  • For Ubuntu 12.04 LTS and Ubuntu 13.04

    To get Hibernation:

    sudo pm-hibernate

    To get Suspend:

    sudo pm-suspend

    "sudo pm-suspend" not working on mint 13 mate :(

    Yeah I think that package was not installed . look for those packages in synaptic.

    the package is installed, I think 'mate-power-manager' is interfering with it.

    Perfect, thanks the pm-suspend was exactly what I was after without having to install all the X related junk with the powermanagement-interface package. All that's needed to use pm-* is the the pm-utils package.

    The drawback of this method is that if you are using the GUI, pm-suspend will NOT block your session, which can be insecure.

    It works on ubuntu 15.10, too.

    works on 14.04 lts

  • You can use the file /sys/power/state to do this. First find out what states are supported:

    [email protected]:_> cat /sys/power/state
    standby mem disk
    [email protected]:~> echo -n mem > /sys/power/state  # suspend to ram
    [email protected]:~> echo -n disk > /sys/power/state  # suspend to disk

    or via dbus:

    # Suspend dbus-send --session --dest=org.gnome.PowerManager \ --type=method_call --print-reply --reply-timeout=2000 \ /org/gnome/PowerManager org.gnome.PowerManager.Suspend #Hibernate dbus-send --session --dest=org.gnome.PowerManager \ --type=method_call --print-reply --reply-timeout=2000 \ /org/gnome/PowerManager org.gnome.PowerManager.Hibernate

    According to this entry in launchpad the above interface was removed. So it would not work anymore in Ubuntu.

    First idea gives me: "bash: echo: write error: Invalid argument" Dbus idea gives output: "Error org.freedesktop.DBus.Error.UnknownMethod: Method "Suspend" with signature "" on interface "org.gnome.PowerManager" doesn't exist"

    I added a small explanation to the `/sys/power/state`-thing. Furthermore the dbus method was removed from Ubuntu so it won't work anymore.

    `$ sudo echo -n mem > /sys/power/state` - `bash: /sys/power/state: Permission denied`

    This works great. For people having problems with this method when using sudo, the "pipe to file", aka ">" is running in your current shell, so it doesn't get super user privileges while your echo did. You'll need to use `sudo -i` first, or pipe to `sudo tee` like so: `echo mem | sudo tee /sys/power/state`

  • To shutdown a system (14.04) from the command line (or keyboard shortcut) use:

    dbus-send --system --print-reply --dest="org.freedesktop.login1" /org/freedesktop/login1 org.freedesktop.login1.Manager.PowerOff boolean:true

    I found this out by playing around with gdbus which can list the interfaces available:

    To list the services available on the bus:

    dbus-send --system --dest=org.freedesktop.DBus --type=method_call --print-reply /org/freedesktop/DBus org.freedesktop.DBus.ListNames

    To find the methods:

    gdbus introspect --system --dest org.freedesktop.login1 --object-path /org/freedesktop/login1 --recurse
  • since 15.04 systemD is the standard init system so there is a new command to be used:

    systemctl suspend

    I'm using Xubuntu 15.04. The command `systemctl suspend` does suspend the computer, but it does not cause the screen to be locked, even though I've checked the "Lock screen when system is going for sleep" checkbox in Settings -> Power Manager -> Security. Anyone have any idea why?

    I've upgraded to Xubuntu 16.04. The command `systemctl suspend` still suspends the computer. Now, it also causes the screen to be locked, if and only if the "Lock screen when system is going for sleep" checkbox in Settings -> Power Manager -> Security is checked.

  • Adam Paetznick's dbus-send answer didn't work as purported for me on lucid; the machine woke up unlocked, even though the gnome-power-manager is set to lock the screen on wake-up. I want the screen to be locked at wake-up, and found that the following does that:

    $ gnome-screensaver-command --lock && pmi action hibernate

    I imagine this does not depend on the gnome configuration, but I haven't tested that.

    Nice. Or `xscreensaver-command --lock` as the case may be.

  • New interface

    …which works in 15.10 Wily, and possibly Utopic and Vivid.

    dbus-send --print-reply --system                         \
        --dest=org.freedesktop.login1                        \
        /org/freedesktop/login1                              \
        org.freedesktop.login1.Manager.Suspend boolean:true

    Helpfully this doesn't require sudo, unlike the pm-suspend command.

    My XPS 13 9350 with Debian/Gnome was with suspend/hibernate issues when closing the lid. After running this command (and the equivalent for hibernation), it went successfully into suspension (and hibernation) and now closing and opening the lid work as expected!

  • Here's how to put a remote machine in standby over ssh:

    ssh -t 'sudo nohup &>/dev/null bash -c "(sleep 1; echo -n mem >/sys/power/state) &"'
    [email protected]'s password: 
    [sudo] password for x: 
    Connection to closed.

    /sys/power/state works in Ubuntu 13.10. pmi gives Dbus error.
