Ill try those other mailing lists, and id like to remind everybody the
solution exists to a extent as i am a developer of Insomnia and
InsomniaX. However i would just like to take this back to basics and
see if anyone can cover the biggest problem.
So if everybody can forget just for a second of the main goal, the
mission at the moment is to find a way to receive the notification of
the lid state changing that does not mix up with the power state
changes.
No, this is not what you are trying to do at all.
What you are trying to do is establish a new mode of operation for the
system; one that is currently explicitly precluded.
Current Apple portables are *not* designed to run without cooling; the
Intel chipset generates too much heat even in its lowest power mode
for the system to survive operation without airflow. As a
consequence, what you are trying to do is to define a mode of
operation that is simply not safe; once the clamshell is closed, users
will assume the system can be put into a bag or under a pile of stuff
with no ventilation, and it will overheat.
Certain Apple portables do support running with the clamshell closed,
but with other constraints applied that make it clear that the user
intends for the system to be awake and that more or less require that
it have adequate access to cooling (keyboard attached, external
monitor attached, explicit wakeup after the clamshell is closed).
The consequences of overheating include emergency system shutdown (the
most common and intended response to thermal distress), but can also
include accelerated aging of components (backlight, fixed and optical
disks, display, cosmetic surfaces) and more subtle effects. The
system is designed to deal with being overheated occasionally and
accidentally, but not as a routine matter of course, which is what
your new mode of operation will facilitate.
Are you terribly surprised that nobody wants to help you?
