Richard,


As far as I understand the code of GPM splitting up GPM in a "daemon"
and a "notication area icon"/applet would not be so hard.

They are pretty independent from each other. 

The "daemon" just has to watch batteries, laptop lid, hardware keys and
take appropriate actions etc. If people run the daemon then they get all
the power management features. 

The applet/"notification area icon" just needs to watch the batteries
(code of the daemon can be reused :-) )and show the status by changing
it's icon and displaying notifications. 

The only message I see that the "daemon" might want to send to the
applet is a message that the system is going to suspend/hibernate and
that is already something we want to do to notify other apps that the
system is going to suspend/sleep and that they need to take appropriate
actions if necessary.

So in my opinion it's not that difficult, or am I missing something?

P.S. Also Network Manager uses this splitup between daemon and
notification icon
