[partly SOLVED] Controlling the uswsusp s2both feature with acpid

Hi,

I am currently using uswsusp on my laptop to suspend to both disk and RAM, which works flawlessly by using the

$ s2both

command.

Now, I would like to use acpid to execute that command and also lock my screen using my display manager which is xdm, whenever I close the lid of my laptop and resume once I open it again.

passing

acpi_listen

and then closing and opening the lid gives me:

button/lid LID close
button/lid LID open

Next I created the following file: /etc/acpi/events/lid_close
It contains:

event=button/lid LID close.*
action=/etc/acpi/actions/lid_close.sh "%e"

The problem is, that I have no idea what the corresponding lid_close.sh script would need to look like in order to do what I want it to do.

I'm aware that I would need an additional event file for the opening of the lid and a corresponding script, but for now I would be happy with automating the suspension/lock process and resuming manually using the power button.

Hopefully you can help me with this.

Thanks in advance.

If you want to lock the screen, on the wiki there is a script https://wiki.archlinux.org/index.php/Pm … or_suspend that uses pm-utils to achieve it.
For the first question, i think in /etc/acpi/handler.sh there are lid open/close options too, so you can put s2both there, while closing.
Hope I understood well your problems, and hope i could help you!

Thanks for the reply.

There is a a part in the handler.sh script which would be activated upon closing/opening the lid.

    button/lid)
       	case "$3" in
	    close)
		#echo "LID closed!">/dev/tty5
		;;
	    open)
		#echo "LID opened!">/dev/tty5
        	;;
	esac
	;;

But as I understand it all it does is print "LID closed!".

How do I make it execute the

$ s2both

command?

Put it in a line under #echo LID closed, before ;; !
Hope this will help you!

Ok.

my /etc/acpi/events/anything file now looks like this:

# Pass all events to our one handler script
event=button/lid LID close.*
action=/etc/acpi/handler.sh %e

My /etc/acpi/handler.sh looks like this

    button/lid)
       	case "$3" in
	    close)
		#echo "LID closed!">/dev/tty5
		s2both
		;;
	    open)
		#echo "LID opened!">/dev/tty5
        	;;
	esac
	;;

and it works!

Didn't think it would be that easy. Thanks for pointing me in the right direction nierro!

Now I just need to figure out how to return to xdm instead of my WM upon resume.

Well, as i said, there is a script for pm-utils, but i think you can use it with acpi too (when the lid gets opened, make that script run!)
Glad to have helped you !

I knew from the wiki that it's possible to use pm-utils with acpid, but I didn't want to use pm-utils becuase it doesn't support suspend to both.

It would be nice if the wiki contained an example for using acpid and uswsusp like I am now.

you mustn't use pm-utils, copy and paste that script in a file, make it executable, then put the path to that script in handler.sh after lid open.
