d3-recipes/tools/acpi

Prerequisites

In order to get ACPI working you'll only need a few things:
• ACPI (comes with Dragora)
• The stuff in this directory
• default.sh
• anything
• pm-utils
• this can be found in tools/pm-utils

Explanation

By default, acpi isn't configured for anything on the base install of D3 Alpha 2 (this might change by the final release), therefore, we must do things to get it to work the way we wish. We are going to make it so that when you close the lid of your C201, it suspends; when you open the lid, it wakes up; when you plug in headphones, it switches alsa to the output driver; and when you unplug headphones, it switches alsa back to built-in speaker output.

In order to do this, you must first get the 2 files in this directory, listed above. Place default.sh into /etc/acpi/, and keep the name the same. Next, take anything and place it into /etc/acpi/events/ - this is an event file and will tell acpi what to do when an event is executed. Since we are only dealing with 2 types of events, lid and headphone jack, we don't need to make separate events; although, you could, if you wanted.

acpi doesn't start upon booting by default, so if you want that, you can create an /etc/rc.d/rc.acpi file with the following command: acpid -e /etc/acpi/events/anything. This will tell acpi what event file to use, although, I believe it defaults to /etc/acpi/events/ anyways.

If you haven't already installed pm-utils, see the section below. Otherwise, you're ready to go!

pm-utils

In order for your machine to actually suspend upon lid closing, you'll need to install the pm-utils package. If it isn't already made and bundled, just build the recipe listed above. pm-utils has a nice command called pm-suspend, which will suspend the machine by loading stuff into RAM (I think). Once that is installed, you're done!
