Bug Description

Binary package hint: gnome-power-manager

This is more of a "wishlist" item at this point, but I am adding it as a bug because it's inconsistent with the UI, inconsistent within itself and I would consider VERY annoying to laptop users. I know it drives me CRAZY because hibernation is painfully slow (several minutes) on my laptops.

Basically the problem is simple, when any laptop is on AC the system idle timeout invokes suspend to RAM, while on battery the system idle timeout invokes hibernation.

I am expecting suspend to RAM (sleep) to be invoked for BOTH instances as described within the gnome_power_manager GUI To quote from both the AC and Battery options, they have identical wording; "Put computer to sleep when inactive for:". This implies that the action taken would be the same (sleep aka suspend to RAM) whether on AC or or battery power. It is not and this was a cause of some serious confusion until I figured out that my computer WASN'T going into suspend, but was instead hibernating.

The fix:
It is literally one setting that can be changed via "gconf-editor > apps > gnome-power-manager > actions" and changing the option "sleep_type_battery" from "hibernate" to "suspend".

If, for some reason, this is desired behavior, then please consider this bug report as a complaint about the GUI wording inconsistency that leads to user confusion and thus unexpected system behavior.

On a personal note, I hope it's not desired behavior on part of the developers as my experience has shown that hibernate is more often broken on laptops than suspend to RAM, especially on my T42 Thinkpad.

This also happens on Lucid. It's a regression from Karmic, where my netbook suspended on idle.
