Probably because X isn't listening on a TCP port. Look for the
"-nolisten tcp" option in whatever config file you're using when
starting X, and remove it.  Just do 'ps awx | grep X' and you'll see
the 'nolisten' option.

Nope. If you ask a question in public, read the answer in public. If
you can't be arsed to come back here and read the answer someone is
giving you in their spare time just out of kindness, you're in the
wrong business.
