    Performing sleep / standby / hibernate / suspend operations from command line in Linux Ubuntu

    Hey guys I have come across a interesting piece of information for you all which I think would be very much useful for you all. So here is a glance for you all have a look at it. you can perform the following functions sleep / standby / hibernate / suspend with the help of command line only. I have tested the following commands in Ubuntu 8.04 using my Toshiba laptop. You can also give a try for the same and do let me know if that would be useful for you or not.

    For the sleep mode you can enter the following code

    Code:
    pmi action suspend
    for hibernate you can look out for the following code

    Code:
    pmi action hibernate
    Now if you are interested in Gnome session first then you can use the following command before pmi.

    Code:
    gnome-screensaver-command –lock
    With the help of these buttons you can create a button (launcher) on a Gnome panel . isn’t it a great idea. hope you all will like this method.

    You haven’t mentioned anything about the suspend and the resume state. Frankly speaking I am new to this pmi. I don’t know how is this pmi action implemented? Till now I was using ‘sudo /etc/acpi/sleep.sh’ and I faced several issues such as wireless was not getting connected when I resumed, the system does sometimes ignore the hdd parameters script. Anyways I will give a try for the commands that you have given, hopefully pmi will be able to give me a much better result than the sudo, that’s what I am expecting.

    See if you are using gnome then the proper solution should be

    Code:
    gnome-power-cmd suspend
    or you can use

    Code:
    gnome-power-cmd hibernate

    Hey sorry to interrupt you all but I have tried with the following commands seems suspend operation is not working properly. Buttons on the GUI for suspend do work well but I will have to run some script in order to invoke some actions for the suspend. So I am just wondering what would be the script for the suspend button/? Well for once I tried running the same script as given above just replacing the words with suspend but it did not work for me, so what do you all have to say about this? Can you please reply to me on this.

    I just want to know how does the suspend button behave can you tell me some of the commands or the output that you get when you click on those buttons? That’s what I want to know.

    Well on typing pmi action suspend the message that I get is "The program 'pmi' is currently not installed. You can install it by typing:
    sudo apt-get install powermanagement-interface".

    So that’s the message that I get. Now recently I got to know that built-in Suspend in Keyboard Shortcuts does not work as well. what to do can you tell me?

    Hey you can try out this one

    Code:
    sudo apt-get install pmi
    after that you can use

    Code:
    sudo pmi action suspend
    now as far as keyboard shortcut is concerned then you can bind the following command
    Code:
    ‘gksu pmi action suspend’
    to a keyboard shortcut, it might ask for the root password.

    I don’t understand how can suspend button ask for a password. Well suspend is a basic operation that is a part of the system, plus in some machines they are automatically set to suspend state. so I think it should not ask for any kind of password at all, what do you all say why should I set a password for such type of actions?

    Hey dude just take a chill pill here is the following command for not entering the password.

    Code:
    sudo apt-get install powermanagement-interface
    Now after that you can run

    Code:
    sudo visudo
    now enter your username in that command line and add it

    Code:
    yourusername ALL=NOPASSWD: /usr/sbin/pmi
    save it. now you will not be able to give any password for that particular command. I hope that’s helpful for you.
