I use encrypted LVM on my laptop. I disabled swap altogether. I placed
the boot partition and boot loader on a separate USB stick which I keep
on my person at all times. The full disk encryption uses a key file
rather than a password. The key file lives on the USB stick, protected
using GnuPG's symmetric encryption option. I also patched my Linux
kernel with something called TRESOR to prevent the full disk encryption
key living in RAM, to help defend against cold boot attacks. I wrote it
all up here:
