There wasn't a request about "free", but I was trying to find out what sort
of swap you had, and whether you have a "resume" option in the grub boot
options. That doesn't matter now, because "free" makes the problem clear.

So you need a bigger swap partition (or perhaps just an extra one - I'm not
sure if hibernate can handle split partitions).
You have ~1.4GB of memory in use, and ~0.8GB of total swap space. Some
compression occurs, and probably some memory that is known to be
discardable will be left out of swap altogether, but there's still no
chance that you can cram the memory being used for all that into your swap.
You've probably been misled by suggestions on the web that if you have so
much real memory, you don't need a large swap space. And for normal
operation, that's true, because if you have more physical memory than you
ever use you won't use swap. But since hibernation essentially works by
swapping out everything that's currently running, you need _at the very
least_ as much swap space as you have physical memory.
