Creating X-window frame from Emacs in TTY

[Nicolas Neuss]

Hello.

I wanted to open an X frame for an Emacs started with "emacs -nw".  This
works for XEmacs, but does not work with Emacs (21.2.1 on Debian Woody).

"M-x make-frame-on-display -> :0.0"  doesn't do anything

I tried also something like

(setq frame-creation-function 'x-create-frame-with-faces)

Then "M-x make-frame-on-display -> :0.0" yields the error

x-create-frame-with-faces: X windows are not in use or not initialized

Is there a way to obtain this feature, maybe using a more recent Emacs?  If
not, why is it disallowed?

Nicolas.
