Are you currently using a Desktop Environment? (If so, which one?) If this is the case, then you typically need to select your language within the Desktop Environment's control system. If you aren't using a Desktop Environment, then how do you login? On the console and then 'startx', or through a Display Manager? (If so, which one?) If you login via a DM, then your regular shell dot files are NOT read during startup. You would need to put your LANG=... in a different place in order to be sure the DM reads it. (And as we have learned the hard way on this mailing list, setting variables won't help you AT ALL if you are using GNOME, because it clobbers them and does its own thing. You *really* need to use GNOME's control system to set your language, if you use GNOME. Which means you are at the mercy of the GNOME control system, and all of its limitations.) If this issue is really "I use foobardm; where do I put variables for my login sessions" then see <https://wiki.debian.org/Xsession> for suggestions.
