[Bug 1201180] Re: Pressing power button turns off the PC ignoring the presence of another session manager

[Martin Pitt]

I think we should completely disable powerbtn.sh if logind is running;
that's much safer than trying to cover all session managers, and much
more correct too as logind itself handles the power button unless a
session manager inhibits it.

** Changed in: acpid (Ubuntu)
     Assignee: (unassigned) => Martin Pitt (pitti)

** Summary changed:

- Pressing power button turns off the PC ignoring the presence of another session manager
+ powerbtn.sh conflicts with logind

** Changed in: acpid (Ubuntu)
    Milestone: None => ubuntu-14.04

Bug description:
  In saucy the PC powers down as soon as I press the power button, it
  seems that systemd is calling "poweroff", but I'm not sure if it's
  doing that in response of some other event (i.e. as callback of a dbus
  call):

  root      4998  0.0  0.0 177932  2104 ?        Sl   20:41   0:00 /usr/lib/x86_64-linux-gnu/systemd-shim
  root      5012  0.0  0.0   4440   624 ?        S    20:41   0:00  \_ sh -c /sbin/poweroff
  root      5013  0.0  0.0   4440   628 ?        S    20:41   0:00      \_ /bin/sh /sbin/shutdown -h -P now

  In any case the caller or systemd itself should be aware that there's
  a session-manager running and that it shouldn't actually directly
  power off the system then.
