# Ubuntu – How to change user’s language (locale) back to English?

gnomelanguagelocale

I made the mistake of trying out some settings through Administration -> Language Support. Now my user account has LANG set to fi_FI.utf8, even though I want to use en_US.utf8. (This is kind-of a follow up to this.)

Listing 1: current locale settings for my user account:

$locale LANG=fi_FI.utf8 LANGUAGE=en LC_CTYPE="fi_FI.utf8" LC_NUMERIC="fi_FI.utf8" LC_TIME=en_GB.UTF-8 LC_COLLATE="fi_FI.utf8" LC_MONETARY="fi_FI.utf8" LC_MESSAGES="fi_FI.utf8" LC_PAPER=fi_FI.utf8 LC_NAME="fi_FI.utf8" LC_ADDRESS="fi_FI.utf8" LC_TELEPHONE="fi_FI.utf8" LC_MEASUREMENT=fi_FI.utf8 LC_IDENTIFICATION="fi_FI.utf8" LC_ALL=  Listing 2: /etc/default/locale which contains the locale settings I want to use: $ cat /etc/default/locale
LANG="en_US.utf8"

LC_TIME="en_GB.UTF-8"
LC_PAPER="fi_FI.utf8"
LC_MEASUREMENT="fi_FI.utf8"


The Administration -> Language support settings look like this:

My specific questions:

• Where exactly (in what file) are the user-specific locale settings (listing 1) stored?
• What is the recommended way of changing that? By editing a file or through some config UI? (I want to use the settings in listing 2.)

The root annoyance which prompted me to ask this: How to change Firefox UI language from Finnish back to English?

I'm using Ubuntu 10.04 if that makes any difference.

• Specify the language at the login prompt after selecting the user. When asked whether to make the selection the new default, select yes.
