--- Comment #6 from Loïc Yhuel <loic.yh...@gmail.com> --- After selecting France as region in Formats, with still American Engligh in Language : - everything is in French (since LANG=fr_FR.UTF-8, LANGUAGE environment variable is set but empty) - `locale` : LANG=fr_FR.UTF-8 LC_CTYPE="fr_FR.UTF-8" LC_NUMERIC="fr_FR.UTF-8" LC_TIME="fr_FR.UTF-8" LC_COLLATE="fr_FR.UTF-8" LC_MONETARY="fr_FR.UTF-8" LC_MESSAGES="fr_FR.UTF-8" LC_PAPER="fr_FR.UTF-8" LC_NAME="fr_FR.UTF-8" LC_ADDRESS="fr_FR.UTF-8" LC_TELEPHONE="fr_FR.UTF-8" LC_MEASUREMENT="fr_FR.UTF-8" LC_IDENTIFICATION="fr_FR.UTF-8" LC_ALL= - ~/.config/plasma-localerc : [Formats] LANG=fr_FR.UTF-8 Adding a second language in the KCM adds to ~/.config/plasma-localerc : [Translations] LANGUAGE=en_US:en_GB Then the LANGUAGE environment variable is set, which makes KDE switch back to English, but Firefox is in French. So : - the Formats KCM sets LANG, instead of LC_* : is there a specific reason for this ? - the Language KCM doesn't set anything, unless there are several languages in the list : IHMO it should set LANG to the preferred language, and set LANGUAGES if there are several languages -- You are receiving this mail because: You are watching all bug changes.
