问题
In emacs octave-mode, when I type M-x run-octave the command freezes so I do C-g to escape. I can switch to the *Inferior Octave* buffer with C-x b but there is no prompt, just the welcome message. C-c i l also does not work.

With Emacs 24.3.1 simply add PS1(">> ") to ~/.octaverc. No need to change the value of 'inferior-octave-prompt'.

From http://savannah.gnu.org/bugs/?41099#comment4:
- Add
PS1(">> ")to~/.octaverc - Add
(setq inferior-octave-prompt ">> ")to~/.emacs.d/init.el(or wherever your Emacs startup is)
This got me going on Ubuntu 14.04, with Emacs 24.3 and Octave 3.8.1. For future readers: according to the bug report, this should be fixed in Emacs 24.4, so if you encounter a similar problem in that or a later Emacs version, it might be something else.

I am having the same problem and can add a little more information which might be useful. I have been using octave daily for months using emacs 23.4 on several machines that had Ubuntu 13.04 installed. Everything worked with the octave mode. A few days ago I updated one of the machines to 14.04 Ubuntu. M-x run-octave stopped working at that point. It freezes partway through the welcome menu. Octave works fine in an xterm. I also tried emacs 24. And I tried upgrading octave. My current version of octave is 3.8.1.
The command I have used successfully in the past to launch the inferior octave was C-c C-i l.
