[Bug 1730606] [NEW] systemd idleaction=suspend not working in multiseat while a screen is showing login prompt

[amk]

Public bug reported:

Ubuntu 16.04.3 LTS, multiseat setup.
systemd:  Installed: 229-4ubuntu21
lightdm:  Installed: 1.18.3-0ubuntu1.1

logind.conf:IdleAction=suspend
logind.conf:IdleActionSec=300

Using multiseat, it is not possible to have gnome settings controlling
idle suspend, as it would ignore the other seat. IdleAction=suspend in
/etc/systemd/logind.conf works well, provided both seats are logged in
or locked.

After boot, or after logout the seat remains showing login screen and
the system never suspends.

loginctl show-session provides IdleHint=yes that allows to determine
whether the user is active. For some reason Active property is yes all
the time.

But for the login screen the show-session does not provide the hint
about seat idling:

$ loginctl show-session c9
Id=c9
User=108
Name=lightdm
Timestamp=Sun 2017-11-05 22:35:37 CET
TimestampMonotonic=13418600852
VTNr=7
Seat=seat0
Display=:1
Remote=no
Service=lightdm-greeter
Scope=session-c9.scope
Leader=12431
Audit=0
Type=x11
Class=greeter
Active=yes
State=active
IdleHint=no
IdleSinceHint=0
IdleSinceHintMonotonic=0

Working on a script to check for IdleHint=Yes and Service=lightdm-
greeter and suspend based on this.

I am marking this as a bug in lightdm because I think it is not
correctly reporting the idle status to the system.
