[Pkg-xfce-devel] Bug#733261: lightdm lost ability not to set LANG

[Martin Dickopp]

Package: lightdm
Version: 1.8.5-2
Severity: normal

Hello,

It seems that LightDM lost the ability not to set the LANG environment
variable with the 1.6.3-1 -> 1.8.5-2 upgrade.

My system is configured as follows:

$ cat /etc/default/locale
LC_CTYPE=C.UTF-8
$ grep -v ^# /etc/locale.gen

de_DE ISO-8859-1
de_DE.UTF-8 UTF-8
en_US ISO-8859-1
en_US.UTF-8 UTF-8

I have disabled the language selector in
/etc/lightdm/lightdm-gtk-greeter.conf (show-language-selector=false).

Observed behavior: After logging in, the LANG environment variable is set
to "de_DE.utf8", which appears to be based on one of the entries (maybe
the first) in /etc/locale.gen.

Expected behavior: LANG unset, or set to something neutral like "C" or
"POSIX".

If I enable the language selector in the greeter application, I can choose
between German or English, but there is still no way not to set LANG at
all.

Best regards,
Martin
