Choice of language

Hello, I have a problem with language. I choose the language for kde to switch between : pt and fr. It works only for the kde application (not icedove, iceweasel, chrome ...) I have modify the script startkde in which I export the variable : LANG In order to obtain the language of kde, i search in the .trinity/share/config/kdeglobals, language to export the good variable. But it seems that when we change the languages the kdeglobals files is modified and the variable language disappear. Thanks for your help.
