First I followed this guide on how to create a swap partition using Disks (I ran into an issue where it said the partition was in use, so I booted from a USB and did that step from there).
It didn't work, so I followed this one on creating a swap file from a partition then this one on enabling hibernation, putting 18gb as the swap size (my RAM is 16gb)
None of them worked. The same thing happens after all of them, whether from a command or a GNOME extension: screen goes black for a few seconds then turns right back on to where it was; the laptop doesn't power off.
I've been at this for a week now and at my wit's end; if anyone has a mere suggestion please let me know.
Here's some info that might be of help:
