We had this question or a version of it not long ago -
see if you can grep the web for gnu.emacs.help and
'<Multi_key> is undefined', then follow the white
rabbit from there.

FTR, I have the compose key up and running and
configurable both in the Linux VTs and in X, including
Emacs both cases, but I don't use the Scroll Lock key
for this (thanks heaven) so I can't help you with
details, but it should definitely be possible, so
keep digging!

OK, found the thread.  Will go through it...  Any short 
answer that will not disable ibus which I also use ?

All I can say is that any answer which involves mentioning Multi_key in
the .emacs file is fundamentally wrong (it might provide a crutch, tho,
of course).

1. Try starting emacs with unset XMODIFIERS and see if the problem goes away
2. Why/what do you use ibus for?

I have tried:

XMODIFIERS="" emacs

and:

/usr/bin/env -u XMODIFIERS emacs 

And both of them get rid of the '<Multi_key> is undefined' emacs message, but that's it.  The letter with the accent, as it appears at the (k)console, firefox, sylpheed-claws client, etc... is not shown in emacs.

Chinese.  Well, I try, as it seems to be quite broken in Linux Mint 17.  Either it is broken, or the OS input method has seen some changes.  emacs does have a Chinese input mode these days although it is really not nice to use.  I'm used to ibus and emacs and have written a lot of text easily that way, on a previous OS (Linux Mint 14, which I still boot when I have specifically Chinese text to write).  Now I would like to use a more recent OS, and add actual pinyin notation alongside Chinese hanzi.

So, so far, no, unsetting XMODIFIERS does not work.

I can't help with the compose key problem, as unsetting XMODIFIERS does
work for me, but I found ibus eventually unusable in Emacs. I've
switched to fcitx for system input, which works okay, but it doesn't
work in Emacs either! The Emacs package manager has an input method
called chinese-pyim which I'm finding quite good -- it takes a bit to
train, but after that it's very nice to use. Or do as I'm trying to do,
and learn the Wubi input method...

Sorry, no actual solution to your problem, but some alternatives...

I would say if half a dozen random apps respect an input method and emacs
doesn't, thats probably worth a bug-report.

Violent agreement.  FWIW, this looks similar to
http://debbugs.gnu.org/17928, which was supposedly fixed in 24.4, so if
your Emacs is older, try a more recent version, and if it's newer, then
try to hysterically hit M-x report-emacs-bug and then calmly fill the
report with as many details as you can.
