LVM on LUKS with SSD/HDD

Hi,

Am attempting to install on a new laptop (MSI GE62 2QD).
Has nVidia GTX 960M (which may be the cause of some issues (lspci hangs and can't be killed) - but that's a separate topic I suppose).

I have a 128GB SSD, and 1TB HDD; with 24GB RAM.

My current idea is to partition as follows - on the SSD:
- /boot (ESP)    [512MB]
- dm-crypt
  - SWAP          [4GB]               (for use only to suspend-to-disk - is 4GB enough?)
  - /                   [20GB]
  - /var              [12GB]
  - /home          [REMAINING]

I will then simply encrypt the HDD drive separately for storing general data.

I began thinking though if it would be worthwhile having, perhaps the SWAP and /home partitions on the HDD.
From what I have read this would be better suited to LUKS on LVM, but I am pretty set on using LVM on LUKS.

Is there any way to achieve the separation of SWAP and /home, while still only needing one decryption passphrase during boot?

Thank you kindly

It would appear that this might be possible...

Perhaps by utilising an encrypted /boot partition(or directory) and then enabling GRUB CRYPTODISK and using a keyfile (so as not to have two passphrases to enter during boot).

I wouldn't place SWAP and /home on the HDD though, but that's a seperate question.
