This issue is present on an artful daily build as well. gdm3 somehow overrides variables set by ~/.pam_environment. (With lightdm it works as expected.)
It should be noticed that the issue is present whether g-c-c or language-selector is used to change the display language. ** Changed in: gdm3 (Ubuntu) Importance: Undecided => High ** Changed in: gdm3 (Ubuntu) Status: New => Confirmed ** Changed in: gdm3 (Ubuntu) Milestone: None => ubuntu-17.10 ** Tags added: gnome-17.10 -- 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/1662031 Title: Switching language and format broken Status in Ubuntu GNOME: New Status in gdm3 package in Ubuntu: Confirmed Status in gnome-control-center package in Ubuntu: New Bug description: In Ubuntu GNOME 16.10 it doesn't matter what display language I select - the effective language is still the one stated in /etc/default/locale. ~/.pam_environment is changed as expected, but the variables set in /etc/default/locale override ~/.pam_environment. In Ubuntu GNOME 16.04 language switching takes effect, but the reason for that seems to be that /etc/default/locale is changed as well, so when a user changes the display language (or format), it changes it for all users on the system. The overriding by /etc/default/locale is probably caused by some other package(s) but g-c-c.
