Bug#782705: release-notes: Interaction between logind and acpid

[Ansgar Burchardt]

Package: release-notes
Tags: jessie

Hi,

having both logind and acpid handle ACPI events can lead to undesired
results, esp. with a non-default configuration. As an example, logind
could try to shutdown the system on a power button press (default), but
acpid was manually configured to just suspend the system.

Please consider adding the paragraph below to the release notes to make
users aware of this issue.

5.6.5 Interaction between logind and acpid

ACPI events can be handled by logind or acpid. In case both
services are configured to handle events in different ways, this
can lead to undesired results.

We recommend to migrate any non-default settings to logind and
uninstall acpid.

Alternativly it is also possible to configure logind to ignore
ACPI events by adding

    HandlePowerKey=ignore
    HandleSuspendKey=ignore
    HandleHibernateKey=ignore
    HandleLidSwitch=ignore

to /etc/systemd/logind.conf. Note that this might change
behaviour of desktop environments relying on logind.
