Preface
I installed hoary (Ubuntu "unstable") because of some specific needs. Netherless, this article should apply to Ubuntu Ubuntu 4.10 "The Warty Warthog" too.
Choosing between APM and ACPI
Right now there is a crucial feature not working with ACPI on linux (2.6.9): suspend to ram does not switch off the LCD backlight. Ubuntu ships ACPI enabled, but without syspend to disk configuration. In effect there ist no working suspend solution working out of the box.
Simply disableing ACPI at boottime activates APM which works fine with suspend to ram and suspend to disk.
