On my primary computer, I have the following set up for emacs and everything works like a charm. I use emacs cvs, auctex cvs, and latexmk on a Ubuntu 14.04. However, I just put the same set up on another computer running Ubuntu 14.04 but LaTeX files are opened in fundamental-mode.
In my init I have:
;; Start server and set directory
(setq server-socket-dir (format "/tmp/emacs1000"))
;; Not sure if (useruid) does anything or the difference between
;; (server-start) and '(server-mode t) in custom

In my latexmkrc, I have
$pdflatex = 'pdflatex --shell-escape -interaction=nonstopmode %O %S
-file-line-error -synctex=1';
In my bash_aliases, I have the following
alias emacs='emacsclient -t -s server --alternate-editor='
alias ipython='ipython3'
Considering both set ups are identical running the same software, why wont this work on a different computer? I run into this problem every time I have to set back up emacs on any of my computers.

When done with a buffer, type C-x #
auctex.elin your init file. If the problem is related to the AucTex mode being absent, I'd start by trying to locate auctex.el, which I suspect is absent from another computer. – wvxvw Mar 23 '15 at 8:30emacsclientand thus Server (3) You havevisual-line-modeenabled and thus Wrap. – Kaushal Modi Mar 23 '15 at 15:39C-h e. Does that buffer list error or warning messages? If so, can you update your question with a list of those errors/warnings? – Kaushal Modi Mar 23 '15 at 15:55(load "auctex.el" nil t t)has theNOERRORargument asnil. So Dustin should be seeing package loading errors ifauctex.el(andpreview-latex.el) are not found. – Kaushal Modi Mar 23 '15 at 15:56
