[Solved] HowTo Configure laptop to sleep when lid is closed

[ShanaXXII]

I was wondering if anyone can help me create a script for sleeping and invoking it when the lid of a laptop is closed.
This is what I have so far, but when I close the lid, it doesn't work :/

Why don t you use tuxonice sources or something like that?

this used to work for me years ago quite well.

or you use a desctop environment which comes with that support out of the box. kde and gnome used to have such features afaik.

assuming you use already a de, why dont you search if it already exists there this feature?

if not tuxonice could be a good starting point

Just to be sure, I take it that

You don't need tuxonice for that.

You are getting the events right, ok? Then all that fails is the mechanisms that ties actions to these events.

Things to take into account:

• acpid needs to be running
  
• acpid, for some reason, needs to be restarted each time you change anything into /etc/acpid/*, so, each time you add, delete or edit a file in there do "/etc/init.d/acpid restart". I am not 100% sure if this applies only to newly created files or it happens also for modified ones. Maybe it only needs a restart when you create an event. So you'll have to check yourself.
  
• not sure, but common sense suggests that everything under /etc/acpid/actions/ need to be chmod'ed a+rx so the scripts will run

Besides that, there's an error in your scripting.

If the scipt I posted doesn't run then hibernation is n9t the problem. Is it marked executable for all users?

[i92guboj]

ShanaXXII, I (and probably everyone else around here) can help you with the scripting part, but that will come later.

The real milestone is getting a basic script to work. If the script is never launched then it's not worth the effort of putting more complex stuff into it. First thing first.

Just to clarify, the script will always run as root (or whatever privileges the acpi daemon grants it) each time the lid is closed. You don't need to be loged in as root or something like that.

Just give that script the same permissions that the rest of the acpi scripts under /etc/acpid/actions have.

just to satisfy my curiousity and for total clarity what happens if you run

Oh, I didn't think that you were including only that line in the script.

Let me explain a bit how it works so you get at least the general idea.

The acpid daemon listen for acpi events, then launches the associated scripts according to the files in /etc/acpi/events/*, in this case, you have associated the "button/lid" event to lm_lid.sh, so, each time such event is triggered the script is run, without discriminating if you are opening or closing the lid.

So, it's up to the script to parse that. You can do that using a case statement, such as in your first example, or some other scripting structure. You should also use $3 instead of $2 (read about "positional parameter in the bash man page). That variable will hold either "close" or "open" when used in your script.

Example:

I corrected the scrip. I got interrupted while writing and it was a bit messed. Dunno if my phone is to blame or if it was me :p

As for the script, well, it is invoked by the acpi daemon, as said. Do you see that "%e" in the event line in your first post? That means "pass the whole acpi_listen output to lm_lid.sh".

So, lm_lid.sh receives a line like this: "button/lid LID close ". In this line, "$3" is the third element, that is "close".

The script says this: if the third element in this line is close then put a value into /sys/power/state, else, if it's open restart my wifi daemon".

And, as said in the other post, that's just an example. I wanted to ilustrate how to handle the "open lid case". You can remove the "else if...then" and "connman" lines. Be sure to keep the "fi", which closes the if sentence.
