However I get this when I run the following so Swap is not a partition, right? What is it now? A file as you noted?

$ grep SwapTotal /proc/meminfo
SwapTotal:       2097148 kB

Thanks so much Ted and I hope that you are doing as well as you can be.

Brian, Very interesting. Is your swap a file or a partition? I just read an article https://bogdancornianu.com/change-swap-size-in-ubuntu/ which sounds like what you describe for making swap bigger. It notes that Ubuntu changed the protocol of swap from a partition to a file. I am using Xubuntu 18.04 and the install here is a swap partition. As shown here from my lsblk:

sda      8:0    0 298.1G  0 disk
├─sda1   8:1    0   199M  0 part
├─sda2   8:2    0 165.4G  0 part
├─sda3   8:3    0     1K  0 part
├─sda4   8:4    0 103.3M  0 part
├─sda5   8:5    0   125G  0 part /
└─sda6   8:6    0   7.5G  0 part [SWAP]
sr0     11:0    1  1024M  0 rom 

So, be careful and check first. I might suggest you ascertain the nature of your system before trying to use the directions you quoted.

Thank you, Ted P.

Brian, A quick look at it seems that it is correct. Swap is a partition, it has to be unmounted to be re-sized, hence the 'swapoff' command. The 'dd' to resize it is an interesting approach, rather than using parted or gparted. If you have used all of the physical drive to install, it might feel clearer to use gparted to enlarge /swap and see which other partition is giving up some room. Check to see if the sample directions were installed to hardware like yours or was it a virtual install? I will have to take a look at the discussion on the Internet. Thank you, Ted P.

Hi All,

My Asus laptop has been freezing up for no reason that I could think of. I found out my swap partition is 2GB and this person solved it by increasing the swap partition to 16GB. I'm reluctant to start messing with partitions, though I have at times, w/o one of you brainiacs look at the procedure. If anyone can look this over I'd appreciate it but no obligations.

Stay safe!

yes Ubuntu 20.04 hangs freeze although I have 8 GB of Ram and i7

I could temporary fix this issue in my side, by expanding swap partition from 2 GB to 16 GB

I am not sure but I think there is problem in Ubuntu 20.04 memory management, here in my side it keep consuming memory, then when both memory and swap are full, the computer start to freeze and hang

the solution steps are:

1- check the amount of swap you have

grep SwapTotal /proc/meminfo

2-turn off the swap process

sudo swapoff -a

3-resize the swap(in my case i expand it to 16 gb)

sudo dd if=/dev/zero of=/swapfile bs=1G count=16

4- attach the swap to partition

sudo mkswap /swapfile

5- activate swap(enable it)

sudo swapon /swapfile

6- see the new swap size

grep SwapTotal /proc/meminfo

done
