With most APM machines, pressing the hotkey causes the BIOS to send a system suspend event. There's no real way for the OS to tell what's caused this (it could be low battery, a closed lid or a sleep key press) and so the correct thing to do is to tell userspace that a suspend is about to happen and then do it. But yes, PMU sleep requests are (last time I checked) generally managed by keycode 142 being generated and userspace dealing with it. There's no equivalent to /proc/acpi/events. This is why I think standardising on the input layer is a more sensible approach than trying to turn input events into acpi ones. -- Matthew Garrett | [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
