Re: pre-suspend notifications?

Ok, it looks fairly simple.  Is there a sensible reason why one must be
root to monitor the apm state?

I'm still kind of confused about how it works.  If I'm listening for APM
events, does that mean that some other process cannot also be listening
for events?  I want to make xscreensaver passively observe the apm
goings-on without influencing them.

I seem to have gotten something in my machine confused somehow; right
now (after having upgraded to apm 3.0b6) I can no longer suspend;
normally, either closing the lid or hitting Fn-F4 will suspend the
machine, but after having run apmd, it no longer does.  Stopping apmd
doesn't make it start working again.  When I attempt to suspend, the
machine keeps running, and after a while (30 seconds or so) makes the
beep-sound that it uses to mean "couldn't do that."  (This is a Thinkpad
770ED running RH 5.2 / kernel 2.0.36.)

Any suggestions on how to diagnose this?  Is there documentation for
this stuff somewhere, besides the man pages that come with the apm
distribution?
