I've never heard that term. I've always heard them called display managers. But, I seem to have gotten this thread mixed up with another where somebody didn't want GUIs at all. I thought when you said "without X" you meant you didn't want a GUI at all and wanted two linux consoles. What you meant was you want a multi-seat, pure Wayland system. My apologies...
Re: [gentoo-user] Re: Multi-user login manager
Is what you want "multi-seat" rather than "multi-user"? e.g., http://www.linuxtoys.org/multiseat/multiseat.html Lots on google.

I don't think that's possible. Thing is, X is obsolete, so if I can have my system work without X installed, that would be nice. If I have to install it, tough that's the way it is.

In the end, I submitted bug #802036 to the Gentoo bugzilla. Ben Kohler
noticed straight away I was still using a very old binutils (hence the
benefit of supplying complete documentation with a bug), and remarked
that problems had been seen with glibc and old binutils. Sergei then
helped with practical suggestions.
I didn't even know you had manually to configure binutils versions, but I
did this, and glibc continued to crash out. Then I tried editing the
ebuild file, removing the check that was causing the crash. This gave me
ebuild validation errors. So, after looking up the man page, I gave the
argument --digest to emerge, and it built. Phew!
So, after catching up on my emerging, I've just got one package which
isn't building, libdrm, but that can wait till another day.

For Debian, I can get configuration files from Debian packages. I wonder if possible to get the kernel configuration files of Gentoo. You can use the one shipped in the sys-kernel/gentoo-kernel-bin package. Thanks. There is only a file - *.ebuild file in this package. From the package, I did not find out what .config file it uses. It seems this script uses the config file of current system. It ships its own .config. The easiest way here is to simply install gentoo-kernel-bin. After you get a system running that kernel, build your own, basing your new config on the existing one.
