Sir I am using Debian wheezy stable AMD64bit version. Can you please suggest how to hibernate my system. Is there any gui to perform the hibernation. Can we configure the system to go into hibernation after specified amount of time as in windows OS if yes so please suggest the procedure.


Regards,
Rupesh.

Assuming you're using GNOME 3 (default), add the "Alternative Status Menu" extension:
https://extensions.gnome.org/extensi...e-status-menu/

Sure. This might depends on your hardware (and choice of drivers) as well though.
Does it work at all?

AGAIN, since you have ignored these things in several of your other posts:

• THERE ARE NOT JUST SIRS ON THIS SITE. Starting off every post with "Sir" isn't a good idea.
• PLEASE try to look things up on your own first
• PLEASE provide details

You don't say what kind of hardware you're using, and if you had just put "debian wheezy hibernate" into Google, you'd have (amazingly!) pulled up lots, alot of which is from the Debian wiki:
http://forums.debian.net/viewtopic.p...61384&start=15
http://packages.debian.org/wheezy/hibernate
http://wiki.debian.org/Suspend

Yes, there are GUI's for it, but (again), you provide no details like which desktop environment (KDE? Gnome? Other?) that you're using, so we can't tell you if there's an applet/plasmoid/whatever for your environment, or where to look.

I'm not sure what "hibernate" means (when not applied to bears). Is that the same as "Lock Screen"? You need to enter your password to unlock it. If it is then with KDE 4.8.4 you just right-click on the desktop and a menu appears. You can then click on the "Lock Screen" item which has a beautiful picture of a lock to its left.
jdk

No. It unloads all unneeded modules while saving its state in RAM (or your drive).
Whether it's useful depends on your hardware.

PS: With systemd you can just do:
# systemctl suspend
# systemctl hibernate
# systemctl hybrid-sleep

pm-utils is mostly used (as a backend) with other init systems.

Thanks Jens. I never heard of it probably because I never used it probably because I never needed it.
ciao,
jdk

Coincidentally I just decided to play with hibernate on my system today and found this guide to be very helpful:
http://chriseiffel.com/everything-li...11-04-mint-11/
Other guides seem to overcomplicate things when for me at least it was a simple matter of:
Create swap partition larger than RAM (It could be the same, but I decided larger for the time being).
Set entry in fstab to mount UUID of swap partition as swap.
Turn on swapping.
Add a resume line to grub using UUID of swap partition.
Add a resume file in /etc/initramfs-tools/confd pointing to the UUID of the swap partition and run update-initramfs.
Now I can (just about) hibernate my machine.
(I still have the problem that my machine doesn't shutdown properly on hibernate so I need to press the power button but that's likely due to one of my external drives being a little faulty or something. Resume works properly, however.)

I am providing my hardware details below
AMD FX 4100 64bit CPU
Gigabyte 78lmt s2p motherboard
8GB DDR3 RAM
500GB harddisk of which I have dedicated 300GB to root partition and 8GB for swap partition


I want to use all the desktops available in wheezy stable and so I want to know whether any GUI utilities are available for commonly used desktops like gnome,kde,lxde etc.,

I recently heard about s2disk can anyone explain about it.

I'm not sure I understand what your problem is?
If you have a swap partition and you did a normal desktop install of Debian as far as I know your system will be set up to be able to hibernate already. If it is then to hibernate your machine you just go to the session menu (where you can log out) and select the hibernate option instead. If there is no option for that then you perhaps need to change some settings in your DE.
If hibernate isn't set up then see the link in my previous post for some tips.
Once you have hibernate working through the session menu then you can take a look at things like hibernating when idle for a period of time. That's not something I've looked into though I have to admit.

I am new to hibernate concept in Linux so I need detailed description about it.

I suggest you read all the links suggested and try to understand as much as you can, then perhaps ask here if you're not sure.
In short hibernating goes like this:
Save contents of RAM into swap file or partition.
Shut down computer.
Then waking it up goes like:
Boot kernel.
Copy contents of swap into RAM.
It really is as simple, and as complicated, as that.

There's little benefit in revoking from sata only.
If it's meant to be a "security/stability" buffer, make your swap twice as big.


It's no more than yet an other wrapper for existing Linux stuff using either your kernel or/and uswsusp (provivdes the ram part in user space).

s2disk => saves the state of your system to disk (not RAM) and powers off.

s2ram => suspends it to ram. (not recommended, full loss of power will cause it to lose data)

s2both => saves the state to disk and suspends it to ram, no need to power off.

Correct me if I'm wrong, but isn't the default in Windows (laptops) more like s2both instead of just s2disk?

I'm not sure on Windows any more -- I haven't owned a Windows machine for a long time so I've not played with it at all.
