What is Pause Button?

I am using Linux 13.2, Gnome 3.14.1 and am brand new to Linux. I can’t seem to figure out the “pause” button. In the upper right of the screen is a pop-out where I can power off the machine. While that pop-out is open, if I hold the ALT keyboard button, the power button in the pop-out changes to a pause button. If I click the pause button, the machine appears to go into some sort of hibernation mode. i.e., it seems to power down, the fans turn off, but some indicator lights on the box remain lit. I can then “wake” it if I want, by pressing a keyboard button or the box’s front power switch. But then, from watching the screen splashes, it appears to go through its whole, complete boot-up sequence, as-if it was powered down completely. In other words, the pause button appears to do the same as the power-off button.

I’m new, so please provide answers in simple terms with clear explanation, since I’m trying to learn and get a better understanding.

Thanks,

Hi
That is ‘Suspend’ to RAM… Fire up yelp (alt+F2 enter yelp and press enter) and search on it :wink:

I guess I’m confused on how Suspend to Ram is supposed to work. I used it the other day. I had many applications left open when I used it. Today I came back to the machine and hit a button on the keyboard. It fired back up and loaded the desktop. Everything I had open and was working on is now gone. I’m confused. I thought it was something analogous to the Windows “hibernate” function. But I’m not sure why everything was gone when it came back up.

Any help?

Thanks,
M Ridzon

Yes, it is like hibernate in Windows.

There are two basic modes: one powers off all except the memory.
Returning is very fast, but it uses some battery. If the battery doesn’t
last, the system crashes.

On most laptops this mode triggers by closing the lid, but this is
configurable.

The other mode saves everything on hard disk, then powers off
completely. It can remain in that state for centuries. On return, the
machine does a reboot, and at some point reads the saved image and
restore it.

On both modes you should be back to all your applications in the same
state. If not, something went wrong.

“Suspend to RAM” should be similar to Windows “Sleep”. And “Suspend to disk” should be similar to Windows hibernate.

Personally, I avoid using either.

I only know how to invoke one of the modes. It’s a desktop machine, by the way, not a laptop. I hover to the upper right corner to power off. When I hit ALT key, the power button changes to a pause button. I then click it and the machine goes to some mystical state of purgatory, presumably Suspend to RAM. But when I hit a key on the keyboard later, it goes through it’s entire boot sequence as-if the machine was completely powered down. When the desktop appears, all of my apps are closed and gone. Strange. I have no idea how or why this is operating the way it is.

Yah, I think I may avoid using it. It doesn’t seem to be working right for me. :frowning:
Thanks for your input.

Then you never should suspend to ram, the machine has no internal
battery. You have to use hibernate, to hard disk. I have been using this
for years in all my machines. I find it very useful.

Well I guess that explains a lot…if I don’t have a laptop, I guess Suspend to RAM won’t work. Can you tell me how to invoke the Suspend to Disk (hibernate) function on my desktop machine? I hover to the upper right corner to power off. I hit ALT key and the power button changes to a pause button for Suspend to RAM. But I’m not sure how to Suspend to Disk (hibernate).

Good point. Unfortunately, I’m not familiar with the Gnome 3, although I
used Gnome previously for about a decade. You need somebody else to
answer that :slight_smile:

I know how to hibernate via command, though. For instance, “sudo
pm-hibernate” does it if pm-utils are installed, which is not a given on
13.2, it is being phased out. But it is what I use.

There is another method with systemd, but I can’t remember it just
now… :-?
