Bug#778464: systemd: HandleLidSwitch=suspend in /etc/systemd/logind.conf ignored since one of the recent uploads

[Axel Beckert]

Package: systemd
Version: 215-12
Severity: grave
Justification: Unexpected behaviour change during freeze which may lead to hardware damage

Dear Maintainer,

   * What led up to the situation?

After 50 days of uptime I recently rebooted my Thinkpad X240. Last two
reboots were on:

# uprecords -Bm2
     #               Uptime | System                                     Boot up
----------------------------+---------------------------------------------------
->   1     0 days, 15:02:01 | Linux 3.18.0-trunk-amd64  Sat Feb 14 22:54:17 2015
     2    50 days, 22:14:05 | Linux 3.18.0-trunk-amd64  Sun Dec 21 12:33:48 2014

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I have HandleLidSwitch=suspend set in /etc/systemd/logind.conf.

Full diff of logind.conf against default contents:

$ diff /etc/systemd/logind.conf.dpkg-dist /etc/systemd/logind.conf
15a16,17
> #Controllers=
> #ResetControllers=cpu
20c22
< #HandleLidSwitch=suspend
---
> HandleLidSwitch=suspend
27,28d28
< #RuntimeDirectorySize=10%
< #RemoveIPC=yes

   * What was the outcome of this action?

Until the last reboot, the laptop went to sleep if I closed the
lid. Since that reboot it no more does so since the reboot which made it
stay running inside its sleeve and starting to heat up.

I can't tell if it would have happened with just systemd upgraded from
215-11 to 215-12 as that happened just 10 minutes before the reboot. So
this issue may be present for a longer time in systemd if only a reboot
actually makes the change effective.

   * What outcome did you expect instead?

Still going to sleep as it did for many months, at least since the start
of the freeze.
