Changing user locale does not work

[kyrios123]

I changed the language from a second user (let's call it user2) from English (United States) to French (Belgium) then I did switch to user2 and everything is still in english instead of french.

If I type locale in a terminal everything is still in en_US.UTF-8 while I expected fr_BE.UFT8

user2@testbox ~ $ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

You need to restart user2 session

 [ll@ll ~]$ ps -efH | grep mate-session
ll           452     431  0 14:07 tty2     00:00:00       /usr/lib/gdm-x-session --register-session --run-script mate-session
ll           468     452  0 14:07 tty2     00:00:00         mate-session
ll          2408    1039  0 14:17 pts/0    00:00:00         grep mate-session
[ll@ll ~]$ kill -9 452

But I changed the locale of another user then I did log in using switch user. This should normally start a new session isn't it?

@kyrios123 If you restart the system and login user2 after changing the language, will the language change take effect?What's more, are you using the mate desktop?
