suspend via Fn+F1 or lid-close behave differently

[Yung-Chin Oei]

Hardware: Dell Latitude D630, with X3100 graphics and iwl3945 Wifi.

Odd behaviour: when pressing the suspend button (Fn+F1), the system hibernates, despite it being configured to suspend. On lid-close, it does however properly suspend as expected. I checked in System -> Preferences -> Power Management, and both for "laptop lid is closed" and "suspend button is pressed" the setting is "suspend".

Expected behaviour: the system ought to suspend instead of hibernate, as specified in Preferences.

The same odd behaviour previously with Ubuntu 8.04, and the same on 9.10.

Further info, update: I get the same behaviour as I get with Fn+F1 when I choose "hibernate" from the quit-menu, so I guess that that's related.

I believe the problem with resuming from hibernation is that the disk volume layout on my system, which consists of an LVM partition with several separately encrypted logical volumes, is something the resume-scripts weren't designed to deal with, so that's actually a separate bug (how do I deal with that? I'm relatively new to bug reporting).

I updated the description: the previous description conflated lots of different issues.

(also, better late than never I guess: thanks Andres!)
