button/lid (no /proc/acpi/events?)

stonecrest · 2006-02-17 03:28:40

I must be missing something obvious but it seem that when I close my laptop's lid, the button/lid section of handler.sh is not triggered. I have acpi running fine, it even seems that other events are successfully triggered (like ac_adapter), but not button/lid. Essentially I'm trying to run 'powersave -u' when I close the lid.

Help please?

You might have to modify the handler.sh script. Try the following as root (you might have to stop acpid first):

cat < /proc/acpi/event

Then close the LID and reopen it. Then check the messages and compare them to the triggers on the handler.sh script. If you can't figure it out yourself, just post the output here.

Thanks for the reply. It seems like this might be part of a bigger problem though, because I don't seem to have a /proc/acpi/event. What I have in /proc/acpi are ac_adapter, battery, button, embedded_controller, fan, power_resource, processor, thermal_zone, and video.

Also, when I start my computer, Arch says that the acpi daemon started successfully. But if I stop it (also successfully) and then try to start it again, it always fails with "acpid: can't open /proc/acpi/event: Device or resource busy".

Here's some sample output from /var/log/acpid which doesn't seem to be very useful. The exiting lines are probably me manually stopping acpid, although it never starts up again unless I reboot..

Now I'm really confused.

I am confused, too. The log indicates that you do receive events, but ACPI events are afaik only captured by /proc/acpi/event. Maybe this has changed, but I doubt it.
