Bug#932047: lightdm: greeter session support for elogind

[Mark Hindley <mark@hindley.org.uk>]

Package: lightdm
Severity: normal
Tags: patch

Yves-Alexis,

Many thanks for updating lightdm's dependencies to use the new logind virtual
packages in closing #922160.

However, the necessary adjustments to the PAM configuration for lightdm-greeter
are still outstanding.

My testing indicates that in order for lightdm greeter's Suspend, Hibernate,
Restart and Shut Down buttons to be enabled, the greeter itself needs to
register a logind session.

For elogind based systems this could be implemented by adding

 session   optional pam_elogind.so

to /etc/pam.d/lightdm-greeter

Or, alternatively and perhaps better for the future, whichever logind
implementation is enabled through pam-auth could be used by sourcing the PAM
common-session.

Patches implementing both of these approaches are attached.

Many thanks,

Mark
