Laptop waking up in bag: go back to sleep script
I have a Debian-derived distro (Kubuntu 8.04) running on a Dell Inspiron laptop. This laptop often wakes from RAM suspension while in my bag. I would like to run a script, upon RAM suspension wake, that would detect if the lid switch is closed. If so, then the script should put the machine back in RAM suspension. Something like this:
Code:
wait 5 seconds
if (lid==open) {
  go to ram suspension
}
return

I do not know how to poll the lid switch, nor do I know how to suspend to RAM from within a script. I have googled but cannot find this. Can someone point me to a RTFM where TFM shows how to do these two actions? Note that other than a short C course in university and a smithering of PHP I really know nothing about computers. I will ask on my distro's mailing list how to have the script run at wake. Thanks in advance.

lm-profiler

LM-PROFILER(8)						      System Manager's Manual						    LM-PROFILER(8)

NAME

       /usr/sbin/lm-profiler - laptop mode profiler

SYNOPSIS

       /usr/sbin/lm-profiler

DESCRIPTION

       This  manual page documents briefly the /usr/sbin/lm-profiler command. lm-profiler is a tool for profiling disk operations. It is a part of
       laptop mode tools and is useful only in relation to rest of laptop mode tools. It helps you to detect programs and  services  that  use	up
       system resources and that cause disk activity, and it allows you to disable them when laptop mode is active.

       When  you start lm-profiler, it will execute a "profiling run", which can take some time. Start lm-profiler when you are working on batter-
       ies, preferably, because that will allow it to analyze the actual situation that it is supposed to optimize. During the profiling run,  you
       can  use  your system normally; however, any disk activity caused by your actions will end up in the profiler's results. When the profiling
       run is finished, you will be presented with a list of programs that deserve your attention, either because they listen on a network  (which
       is  not	usually  useful when you are working offline) or because they caused disk activity in a disk-spindown-unfriendly pattern. When lm-
       profiler can guess an init script that belongs to a program, it presents you with the opportunity to disable the program when you are work-
       ing  on battery. It does this by placing a link to the init script in /etc/laptop-mode/batt-stop. Any programs that lm-profiler cannot find
       an init script for is simply reported, so that you can stop the program manually if you want to.

       WARNING ABOUT DISABLING PROGRAMS: It may not be safe to disable some programs. They may be needed for proper operation of your system. Dis-
       able services only if you know what they do and why you don't need them.

FILES

       /etc/lm-profiler.conf
	      lm-profiler retrieves its profiling rules from this file.
