Bug Description

I noticed that with Ubuntu Server 13.10 when I press the power button, it flashes "acpid exiting" on the console and then does an immediate hard poweroff. Filesystems are not umounted and require recovery on restart.

Upon further investigation I found that apparently both acpid and systemd-logind attempt to handle the event with the described result.

Disabling either acpid (by deleting /etc/acpi/events/powerbtn) or systemd (by adding HandlePowerKey=ignore to /etc/systemd/logind.conf) fixes the issue.

Note: I was reproducing the issue using clean 13.10 server installs in KVMs. http://superuser.com/questions/677331/unsafe-power-off-on-power-button-pressed/746841#746841 indicates that others have observed this with non-VM installs.

Also #1219338 and #1245327 may be related.

I can't reproduce this in Trusty. Can you see if you can reproduce this in Trusty (14.04)?

This is not related to the acpi-support package. The script in question belongs to acpid itself, not to acpi-support.

no longer affects: acpi-support (Ubuntu)
