Hello. I have zhangwe...@esmeralda:~$ grep --invert-match ^# /etc/locale.gen
zh_CN.UTF-8 UTF-8 en_US.UTF-8 UTF-8 de_DE.UTF-8 UTF-8 For most applications, I can start it in any language I wish to use. e.g. if I want to start abiword in en_US, I can do this: zhangwe...@esmeralda:~$ LANG=en_US abiword However this method doesn't work for firefox and thunderbird. Both always starts in German (note German is the last, a.k.a. least preferred language for me, in /etc/locale.gen) I checked that I do have thunderbird installed with linguas_en_US (see below emerge output). If it is installed with that language version, it should be able to run in that language version. How can I start thunderbird in en_US? zhangwe...@esmeralda:~$ sudo emerge -pv mail-client/mozilla-thunderbird These are the packages that would be merged, in order: Calculating dependencies... done!
