Isn't that provided by the DE. What specifically does the DM do for you?

I run X and a WM, but I don't use them to login. Just a VC.

That's because there are 4096 different values of salt that could have
been chosen.

I don't understand any of that.

$ ls -l /etc/apt/sources.list
-rw-r--r-- 1 root root 981 Jan 20  2018 /etc/apt/sources.list
$ 

But in any case, you can cat it and then copy/paste it,
as you just did, above, for apt update.

In which case, can you quote your reference for where said person
mentioned it.

Whether you've *used* LUKS is irrelevant. You might still have
*heard something* about it, and thought it was about passwd passwords.
I can recall things being written about VM here, but was it Virtual
Box, vbox, qemu, kvm, virt-manager—not having used any VM, my memory
doesn't distinguish between them.
