Description

The following sentence might pretend that the locked screen interacts badly with the emergency shutdown:

"When the screen is locked, it’s not possible to quickly shutdown the computer properly (i.e. with memory erasure): the computer’s shutdown button is inhibited, and the fact to put out Tails’ device does not shut the computer down."

sajolida says “I tested that and it works on Tails Jessie” so I think we can close this ticket.

Unplugging the device works. But the power button does indeed not work in the lockscreen. Is this a blocker? I could not find out how to get signalled that the power button was pressed. There are some related signals on dbus from systemd-logind, but nothing we could use for this. Maybe someone who knows this already could explain how the emergency shutdown gets triggered by the power button currently? anonym maybe?

I don’t think that’s a blocker.

Marking this as “Info Needed” because I understand that you assigned it to anonym for more info (and not for coding). Also putting it for 2.6, to get a quicker answer.

Agreed.

First of all, what we call “emergency shutdown” is the one triggered by plugging the boot device out. What is triggered by the power button is normal shutdown. I’m pretty sure it’s handled by systemd-logind.

#14 Updated by sajolida 2016-09-04 01:57:52

I think that triggering nothing when pressing the power button while the screen is locked is no problem. So maybe this is Ready for QA?

segfault: So maybe we can close this?

> segfault: So maybe we can close this?
If the “emergency shutdown” is only the one triggered by unplugging the boot device, this is solved and can be closed. (I wonder why this ticket was reopened in the first place, because Bug #7334#note-13 is only about the power button not working)
