Comment 25 for bug 1631750

I have what seems to be a variant of the same problem, but not fixable with the workaround mentioned above. I upgraded a couple of days ago from Ubuntu Gnome 17.4 to Ubuntu 17.10, and now various of my global locale settings are incorrect in Gnome Shell 3.26. I set all the LC_* variables to "en_GB.UTF-8" in /etc/default/locale, but the shell opens with a lot of them changed to Spanish equivalents (I live in Spain):

bash-4.4$ locale
LANG=en_GB.utf8
LANGUAGE=en_GB:en
LC_CTYPE=en_GB.UTF-8
LC_NUMERIC=es_ES.UTF-8
LC_TIME=es_ES.UTF-8
LC_COLLATE=en_GB.UTF-8
LC_MONETARY=es_ES.UTF-8
LC_MESSAGES=en_GB.UTF-8
LC_PAPER=es_ES.UTF-8
LC_NAME=es_ES.UTF-8
LC_ADDRESS=es_ES.UTF-8
LC_TELEPHONE=es_ES.UTF-8
LC_MEASUREMENT=es_ES.UTF-8
LC_IDENTIFICATION=es_ES.UTF-8
LC_ALL=

Switching from gdm3 to lightdm makes no difference. Starting fvwm instead of Gnome on xorg shows that the problem doesn't exist there, but -- to my surprise -- it does exist if I start Gnome flashback on Compiz. I can't try Unity, as it says my stored display settings prevent it from opening.
