나비(nabi)에서 세벌식(최종)을 쓰려면 GTK_IM_MODULE도 설정?

nabi를 설치했는데 나비 applet에서 한글자판을
세벌식 최종으로 해도 firefox에서 계속 두벌식자판으로
입력이 됩니다.
export GTK_IM_MODULE=hangul3f를 해주면 제대로 쓸 수 있던데
(질문1)원래 이 변수까지 설정 해주어야 firefox에서 nabi를 이용하여 세벌식을
쓸 수 있나요?

제 nabi의 config화일은 아래와 같습니다.

$ cat ~/.nabi/config
xim_name=nabi
x=0
y=0
theme=KingSejong
keyboard_table_name=세벌식 최종
keyboard_table_dir=/usr/share/nabi/keyboard
compose_table_name=default
compose_table_dir=/usr/share/nabi/compose
candidate_table=/usr/share/nabi/candidate/nabi.txt
triggerkeys=Hangul,Shift+space
candidatekeys=Hangul_Hanja,F9
dvorak=false
output_mode=syllable
preedit_foreground=#FFFFFF
preedit_background=#000000
candidate_font=Sans 14

그리고 다음은 /etc/gtk-2.0/gtk.immodules의 내용인데
(질문2) GTK_IM_MODULE을 설정하기 전에는 물결친 부분때문에
nabi에 세벌식설정을 해주어도 계속 두벌식으로 나오는 것인가요?

(질문1다시)
nabi에서 아무리 설정을 바꾸어도 세벌식이 안써지길래 결국

$ export GTK_IM_MODULE=hangul3f
