Ubuntu 10.04 Sleep Instead Of Hibernate When Idle

Ubuntu has an incomplete power management tool built in.  Some of the things you CAN'T configure is the ability to sleep instead of hibernate when the computer is idle for a period of time (the period of time is easily configurable in the power-settings dialog).  Here's how to modify Gnome's advanced power settings using the gconf-editor:
  1. Run the command gconf-editor (press [alt]-[f2], type gconf-editor, and press [Enter])
  2. Browse to /apps/gnome-power-manager/actions/critical_battery
  3. Change the settings.  Possible values are "hibernate", "suspend", "shutdown" and "nothing".
