Re?? Is there any way to STD in Debian?

[YOYO]

Hi Alexander, Eben, and everyone in list,
Thank you for your replies.
The Debian 12 is running in VirtulBox 7.0.20. And I only assigned 2048 MB 
RAM to it.
I'm pretty sure that I have setup a big enough SWAP of around 8 GB when 
installing Debian 12.
When I click "Sleep" button in Windows running in VirtualBox 6.x, the virtual 
machine will light the screen up again once the screen is off. However, in this 
case, Debian 12 doesn't light the screen up nor power-off the virtual machine. 
So the virtual machine goes into a state that OS is not running, power is still 
on. And I have no way to wake the OS up. All I can do is to fouce power-off and 
re-start it, just to found all running tasks gone.


Best Regards,
Richard

                Hello everyone,
      Recently, I need to cut off power supply with all my running        tasks 
saved.
      But it seems that the hibernate mode provided in Debian only        
allows me to&nbsp;
      Suspend to Ram(STR, or S3 mode in ACPI).
      Is there any way to Suspend to Disk (STD, or S4 Mode in ACPI)        in 
Debian?
      Thank you for your replies in advance.

        Do you have a swap partition? It has to be sufficient in size and is    
necessary for Hibernation to work.
    You need to edit "/etc/initramfs-tools/conf.d/resume"    file to provide an 
UUID of a swap partition, or a path,
    in case of LVM, to a swap partition and run:
    # update-initramfs -u
    
    &nbsp;&nbsp;&nbsp; Example for traditional disk partitioning scheme:
    $ cat /etc/fstab | grep -iE "swap"
      UUID=e990fa6d-3f82-4d65-b6a1-542e240718fc&nbsp;&nbsp;&nbsp;&nbsp; 
none&nbsp;&nbsp;&nbsp; swap&nbsp;&nbsp;&nbsp;      
sw&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0
      
      $ cat /etc/initramfs-tools/conf.d/resume 
      RESUME=UUID=e990fa6d-3f82-4d65-b6a1-542e240718fc
    
    &nbsp;&nbsp;&nbsp; Example for LVM partitioning scheme:
    $ cat /etc/fstab | grep -iE "swap"
      /dev/vg0-nvme/lv1-swap&nbsp; none&nbsp;&nbsp;&nbsp; 
swap&nbsp;&nbsp;&nbsp; sw&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0
      
      $ cat /etc/initramfs-tools/conf.d/resume 
      RESUME=/dev/vg0-nvme/lv1-swap

While that is the easiest way by far, I was recently told that the
"resume-from" kernel option can enable hibernation to a non-swap area.&nbsp; I
think.&nbsp; I have not done this.&nbsp; Look in the archive for a thread this 
month
(9/2024) entitled "hibernate area".

But yes, I use hibernation every night.
