In fact, having the swap space twice the size of your RAM is only a guideline. Actually with 8 GB of physical RAM you won't need much swap space: you might want to keep the one and delete the other partition. If you want to use swap encryption you should keep the `cryptswap` if not, keep the other one.

However, **to hibernate you must have at least the same amount of swap *free* as you do RAM *used*.**
