Public bug reported:

In gnome-shell, the hardware power button does not open the interactive
power menu. It sleeps the computer instead.

The configuration backend to customize this behaviour was intentionally removed 
in commit [50564cde49ca2][1] (for [bug 753713][2]). After [some 
discussion](, it's returned 
in [gnome-settings-daemon

Unfortunately, 3.20 is not in the [16.04 ubuntu
(however there is a 3.20 release for Yakkety 16.10).

Can 3.20 be released in xenial-updates?

Removing this functionality is a disruptive change and it appears it was
introduced in the Xenial LTS release (3.17 was not in Wily). While I
understand gnome doesn't follow Ubuntu's stable release strategy and
this is one in a large system of applications, can we get gnome-
settings-daemon upgraded to 3.20 in Xenial?


Use case scenarios for why this is disruptive:

* [Accidentally hitting the power 
 sleeps the computer without recourse. The interactive menu gives you 60 
seconds to cancel.
* Laptops can already suspend when the lid is closed. While the power button 
can be configured to hibernate instead of sleep, my laptop does not support 
hibernate. Now I have a nonfunctional button (when configured to hibernate) or 
two ways to do the same action.
* Laptops with low battery life cannot last long in suspend state. (And again, 
hibernate does not always work.)
* The initial change was made to make the media buttons do what their labels 
say, but the "power" button no longer controls powering off the machine.

Removing "shutdown" from the list of configurations is reasonable on the
grounds that it is destructive, but removing "interactive" doesn't
follow since it's the least destructive. The power button was the most
convenient way to invoke that menu.

Thank you for your consideration.
