You have not read my first posting in this thread and also not read the
threads it was linking to, right?

I already mentioned the LVM+encrypt option, but:

1. This will create an UNENCRYPTED /boot partition. This is not exactly "full
   disk encryption"
2. With this LVM+encrypt pseudo-full-disk-encryption, power management no
   longer works. Dimming LCD no longer works. Fan is running even in the
   suspended mode etc/pp. All this is not really a hardware problem, because
   all of this works fine if I use UNENCRYPTED install.

And you also have not really tested the steps you are suggseting, right?

In this "manual install" menu, there is no way to create anyencrypted
partitions. Even if you use another distro to create the luks partitions,
there is no way to put any filesystem onto them.

As I already wrote: If there is ANY way to create encrypted /boot and swap,
then the developers have done a damn good job in hiding this functionality.

If you can find a way to do this, please provide EXACT steps how to do it.
