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.
