/etc/default/locale and ~/.pam_environment are the only files which are written to via the GUIs, and both of them look normal to me. The locale output, however, is not consistent with those files. With that ~/.pam_environment file it ought to look like this:
LANG=en_US.UTF-8 LANGUAGE=en LC_CTYPE="en_US.UTF-8" LC_NUMERIC=de_DE.UTF-8 LC_TIME=de_DE.UTF-8 LC_COLLATE="en_US.UTF-8" LC_MONETARY=de_DE.UTF-8 LC_MESSAGES="en_US.UTF-8" LC_PAPER=de_DE.UTF-8 LC_NAME=de_DE.UTF-8 LC_ADDRESS=de_DE.UTF-8 LC_TELEPHONE=de_DE.UTF-8 LC_MEASUREMENT=de_DE.UTF-8 LC_IDENTIFICATION=de_DE.UTF-8 LC_ALL= So the variables set by ~/.pam_environment seem to be overridden somehow by settings somewhere else. Actually, I see in the attached ProcEnviron.txt file that every single locale category has been set explicitly (to German) - also variables which are not set by any of those two files such as LC_CTYPE and LC_MESSAGES. More questions: Are you possibly accessing the PC remotely from some other machine via SSH or something? What's the output from these commands: dpkg-query -W gdm3 cat /etc/environment -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1778225 Title: Can't switch UI language for single users, only system-wide Status in gnome-control-center package in Ubuntu: Incomplete Bug description: The title says it all ... I tried to switch the language of the user interface to English instead of German for a single user, which did not work. Applying the new language system-wide did the job, but forced all other users on that pc to have their graphical sessions in the new language too.
