Looking for an "EASY" way to enable hibernation on my laptop

So far, all I've done is increase my swapfile to be 1.5 X16GB RAM. Any help will be really appreciated! (I have the feeling that easy is not how I will define this task)

Have not tried it--but searching around sounds like swap partitions are easier.

See this post for 18.04, for instance Hibernate and resume from a swap file - Ask Ubuntu

Do you have enough disk spare to use a dedicated partition? Gparted handles resizing fairly simply, though backups before are advisable. You'll need to know about partitioning and whether you are using MBR or GPT before also.
