Qubes-OS idle shutdown timer and shutdown when laptop lid closed

Is there a way to make it so that
when I close my laptop lid Qubes shuts down
and when the laptop is idle for a set time it automatically shuts down
I enjoy the benefits of Lux encryption when I am putting my laptop at rest and do not use the screensaver

I did not see this anywhere and could not figure out the necessary combination of settings to make both of these things work despite the “power manager”/“screensaver” settings for dom0
It seems as if the power manager and the screensaver do not actually power off the machine based on the settings.

I didn’t try this on Qubes, but in general it works on systemd-based systems:
Edit /etc/systemd/logind.conf and add:

IdleAction=poweroff
IdleActionSec=30min

(replace 30min with your preferred interval, of course)

EDIT and Update #1: it works on my heavily used and modded 4.1.2 installation. Will test on 4.2rc4.
EDIT and Update #2: works on 4.2rc4 too.

The behavior is a little weird: I had the IdleActionSet=10min, and the (stock, blanking, locking) screensaver at 10 minutes too. The laptop shut itself down after 20 minutes! Like it started the Idle timer when the screensaver kicked in and locked the screen.

I set that. Is there a way to make it so that when the lid is closed the computer shuts down?

nvm I see now in logind.conf there are commented out commands that are useful thank you!
