I set my computer ( a Dell Dimension 9150, Nvidia graphics card, running non-proprietary drivers) to hibernate after 2 hrs inattention,
Every time it initiates a hibernation it simply reboots.
Check the basics first…
Swap space configured?
cat /proc/cmdline
How much swap space is there?
cat /proc/swaps
There should be an appropriate ‘resume=’ entry.
sam@linux:~> cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-4.4.114-42-default root=UUID=a0fdab26-1fe7-488a-82cf-0f4ddd1e29e8 resume=/dev/sda5 splash=silent quiet showopts
sam@linux:~> cat /proc/swaps
Filename Type Size Used Priority
/dev/sda5 partition 2102268 0 -1
Ok, and is swap big enough? How much RAM in the system?
free -m
sam@linux:~> free -m
total used free shared buffers cached
Mem: 3510 3163 347 26 0 2174
-/+ buffers/cache: 988 2521
Swap: 2052 0 2052
Not enough swap for the RAM you have. Hibernation will never succeed. It needs to be doubled in size.
This can also be used for a quick check…
# cat /proc/meminfo|grep -i total
Some more advice on this here:
https://itsfoss.com/swap-size/
*See the Ubuntu reasoning (with hibernation) as well.
So I created a flat swapfile of 5 gig in /home.
on execution of
“swapon /home/swap/swapfile”
I get a result of
“linux:/home/sam # swapon /home/swap/swapfile
swapon: /home/swap/swapfile: insecure permissions 0644, 0600 suggested.
swapon: /home/swap/swapfile: read swap header failed”
I don’t know why you’re trying to use a swap file instead. Is it not possible for you to use gparted to repartition for a larger swap partition? Apart from the permissions that need adjusting, some additional steps are required to use such a swap file for hibernation purposes. I don’t have direct experience with this, so you’ll need to do some reading…

According to the web, XFS cannot be resized no matter what tool you use!
So… I deleted the /home partition and resized the swap to 10 gigs, then recreated the /home partition as ext4.
Still no joy the system reboots when attempting to hibernate.
Show us with definitive output please…

Ok, that looks as expected.
What happens if you attempt to hibernate (as user) using the following?
systemctl hibernate
You might find some clues from an examination of the system journal from the previous failed hibernation perhaps…
sudo journalctl -b -1 -r
systemctl hibernate:
initiates a reboot!
sam@linux:~> sudo journalctl -b -1 -r

I note from the output that your machine is a Dell DXP051. A BIOS issue prhaps? Have you checked for any BIOS settings that could be impacting here?
I recall a similar thread which you may like to review. The OP found that upgrading the kernel helped with resolving the issue.
Sorry if I broke a forum’s rule but I did not want to open a new thread.
Until now I thought that I only need a swap if I did not have enough memory (or my memory is not enough for what I do). It seems that until now I misunderstood the swap.
After I read this thread and the links, I have a question: is it absolutely necessary to have a swap?
It seems that the more you read you realize you do not know enough.
Thank you.
For hibernation, yes, and it should be as big as your RAM. That’s because when hibernating, the RAM will be copied to swap and then the system shut down.
Otherwise, it’s not strictly necessary, especially not if you have lots of RAM. Although it still can improve things, as things that are currently not needed can be swapped out freeing more RAM for more useful things.
Thank you for the answer.
I did not use hibernation at all and I have 16 gb ram.
So, I think I will not use swap.
