Power Management Notifications in Linux

Question

Which are the approach (simplest possible) that we can use to get notified for Power Status changes (for instance when computer goes to sleep, hibernate, etc.) in Linux based systems?

I will need this mainly for persisting some state before sleeping, and of course, restoring that state once the computer wakes up.

Why do you need such notifications? – thkala Nov 09 '11 at 17:00 — thkala, Nov 09 '11 at 17:00

You can get all these events by just configuring your acpid to send them via socket, for example.

There's an official specification document that describes all possible events and circumstances. An extensive read though.

Thanks, seems to be feasible. I'll take a look at this approach :) – Santi Agüero Nov 09 '11 at 19:10
