GUI cannot activate input method fcitx even if disabled C-SPC

[cmal]

ubuntu 12.04 LTS amd64
ibus works perfectly in emacs23
but when I uninstall ibus and switch to fcitx, fcitx cannot be activated when using GUI.
fcitx works perfectly in other places.
I have added (global-set-key (kbd "C-SPC") 'nil) in custom.el
when hit C-SPC, minibuffer shows: C-SPC is undefined.
when using "emacs -nw" or "emacs -Q" to start emacs, fcitx works perfectly and does not have any problems.

I'm not familiar with ibus or fcitx, but custom.el is the wrong place to add that "global-set-key" setting. Try putting it in init.el instead, and restart emacs.

@caml, use shift-space as hotkey of fcitx, this config works for me perfectly for ages.
This is part of my ~/.config/fcitx/config

[Hotkey]
# Hot key of Triggering Input Method
TriggerKey=SHIFT_SPACE
# Hotkey of Switching Chinese and English Mode
ChnEngSwitchKey=L_CTRL

BTW, you can use eim when fcitx not available.

thank you, chen bin.
and thank you, Steve.
Your methods both works. Thanks a lot.

I don't think it's a good solusion. I NEED use the C-SPC to swtich the input-method like ibus. So the real problem is how to stop emacs to capture C-SPC event. Even If we (global-unset-key (kbd "C-SPC")), emacs still catch the event and throw "C-SPC is undifined message" !!

@gadmyth That doesn't sound specific to this emacs.d config, though, right?

To anyone struggling with this issue: you have to set LC_CTYPE to something Chinese (zh_TW.UTF-8 did the trick in my case).
