Package: lightdm
Version: 1.10.3-3
Severity: important
Dear Maintainer,
Since jessie, lightdm has broken my setup (breaking network printing,
authorized with Kerberos in my case) because it does not source
/etc/environment when starting a session, as any DM should.
My setup did work correctly previously with wheezy (its lightdm version
correctly sourced this file).
For me, the fix was to remove the "envfile=/etc/default/locale" argument
to pam_env.so in /etc/pam.d/lightdm. This change is Debian-specific, and
comes from this patch version:
http://anonscm.debian.org/viewvc/pkg-xfce/goodies/trunk/lightdm/debian/patches/05_debianize-pam-files.patch?revision=7308&view=markup
Furthermore, the comment above is inconsistent with the line described.
I really do not know what /etc/default/locale has to do with the whole
environment: it is just a small part of it (I do not even know where
this is sourced; still, I get the correct locale even with my fix).
This bug and its solution look quite like the fix proposed in #784158
(apart from the user environment sourcing; I have no opinion on this)
but it has been dismissed has "fixed-upstream" (which is strange as it
seems Debian-specific) and "wontfix" which is really a big mistake, thus
the severity "important" here, as it is *really* breaking a rather
fundamental function, to me.
Please explain the rationale behind the /etc/default/locale thing or
please fix it for jessie (I lost *a lot* of time on this).
Thanks,
-- benjamin
