As you were told on the Enigmail list, thousands of people have found
that GnuPG 2 works well with Enigmail on Linux.  I demonstrated this to
you by sending to the list a correctly-signed email written on an Ubuntu
12.04LTS system using GnuPG 2.

If you're having troubles getting Enigmail to work there are many people
who are willing to help you.  However, talking about how GnuPG 2 is
completely broken on Linux, and how Enigmail is clearly too buggy to
use, and everything else, is not exactly constructive.

GnuPG 2 works just fine for the overwhelming majority of Linux users.  I
don't know what your particular problem is, but it can likely be resolved.

If it were encrypting to the private key, this would be a digital
signature.  That's what a digital signature is -- an encryption
operation using the private key.  I don't understand your complaint.  If
you're saying "Enigmail will sign emails," well, yes, it's designed to
do that -- but I don't think that's what you're trying to say here.

I have been using Enigmail with GnuPG 2.x for literally years, and over
that time I have had no trouble interoperating with people using other
Linux distros or even entirely different operating systems.  This is the
first time in all my years of using Enigmail that I have heard anyone
tell me that Enigmail's output is not interoperable with other systems.
 This is not to say that you're not having trouble with Enigmail -- far
from it! -- but claiming there is "no compatibility" is a fairly extreme
claim, and I'm going to need to see some supporting evidence.

GnuPG 2 is not an add-on widget to GnuPG 1.4.
