Thanks for your response. To clarify, my X server is working fine and
accepting TCP connections, as demonstrated by the fact that emacs
started without the -nw option, with the same display specification,
works correctly. The problem is with emacs when started with the -nw or
--daemon options, and then later using make-frame-on-display. This
problem first appeared in a recent version of emacs, I think around
version 24. From memory, version 23 was definitely working, but I'm not
sure whether earlier versions of 24 were working.

I can't actually try using a Unix domain socket connection as you
suggest in my environment, since the emacs process and the X server are
on separate hosts. If it would help, I could configure a test host with
both emacs and an X server, and test whether the bug also occurs with
Unix domain X connections.
