I told it to shutdown when battery power is critical, but
I'm wondering who the heck recognizes that. I don't run
a gnome session, so is there some daemon that needs to
be working for it to actually shutdown cleanly?
If you're not running a GNOME session, I don't think the GNOME power
settings will be relevant to you. GNOME manages power in
gnome-settings-daemon.
If your UPS is an APC model, you can use apcupsd. However, I recommend
"nut" since it handles a wide variety of UPS types. IIRC, you'll want
to install the "nut" and "nut-client" packages.
