AFAIR, it could be in any number of places, because the X startup
scripts could source any file Ubuntu wants them to.  The classical
places are as below:

  . /usr/lib/X11/app-defaults
  . files in the directory pointed to by the XAPPLRESDIR environment
    variable
  . a file in your home directory named literally "Emacs"
  . explicit arguments to xrdb invocation when the X session starts
  . a file pointed to by the XENVIRONMENT environment variable

Also look inside the file .xinitrc, if you have it, and in
/etc/X11/xinit/xinitrc, for possible clues.

Once again, Ubuntu could (and probably did) hack the heck out of this
stuff by providing their own resources somewhere and arranging for the
X session to source them at startup.  That's Ubuntu-specific, so I
have no idea, as I don't use that system actively.  Various Google
hits seem to indicate that the /etc/X11/Xsession.d directory might
hold at least some of the relevant stuff.  The Xsession man page might
help.

That is probably a good idea anyway.
