[Pkg-xfce-devel] Bug#826397: lightdm: Environment is not overridden for greeter session

[Vladimir Kudrya]

Package: lightdm
Version: 1.10.3-3
Severity: normal

Dear Maintainer, I'm trying to set custom language of lightdm greeter
while leaving system-wide defaults alone. Lightdm manual suggests that
it takes language from /etc/environment, so it should be possible to
override them in /var/lib/lightdm/.pam_environment. Same mechanism was
suggested on Archlinux forums: https://bbs.archlinux.org/viewtopic.php?id=165381
But that does not happen. Greeter process is started with system-wide
language variables. Perhaps some debian-related mechanism is involved.

/etc/environment: empty

/etc/default/locale:

	#  File generated by update-locale
	LANG=en_DK.UTF-8
	LANGUAGE="en_DK:en"

/var/lib/lightdm/.pam_environment:

	LANG=ru_RU.UTF-8
	LANGUAGE=ru_RU:ru
	LC_TIME=en_DK.UTF-8

Expected results: greeter starts with LANG=ru_RU.UTF-8...
Actual results: greeter starts with LANG=en_DK.UTF-8...
