Swap partition after installation

Hello all, is it possible to make a swap partition AFTER I have done installation?
because I didn’t allot any space for swap while installation.
since I have 4GB RAM so I don’t want it to freeze up when enough memory isn’t present

Hi!
It can if you have any allocate space in your disk using gparted or any other partition manager, after that, you need to add the swap partition to /etc/fstab and enable swap.
If you don have any allocate space, you can create a swapfile in your system, it work the same way.

I would recommend to consider systemd-swap.

Why does it say,
Memory: 0MB ? :thinking:

Thank you for the steps.

Currently or let’s say at the moment you not need swap space as your programs are happy with the RAM you have. :grin:

time to make them unhappy now :crazy_face:
