ACPI doesn't detect lid close event until another ACPI event happens.

This has only started in the last few days and I don't know what might have caused it.

If I close my laptop lid, nothing happens until another ACPI event happens, such as pressing the power button or un/plugging the A/C cord. Then it will suspend and wake up immediately (because the lid is actually open by this point).

Does anyone know why the acpi event is getting stuck in the tubes? Better yet, why is this happening now when it has been working perfectly for months?

BUMP?

I have tried downgrading acpi and acpid. I've also tried upgrading my kernel to 2.6.39-ck from 2.6.38.8

This reminds me of Schrödinger's cat.  With the lid closed, how can you know ??  wink

Anything interesting in dmesg or the acpi logs?

Totally off topic. Sorry. I realize it's a thought experiment describing a paradox, but I've always wondered if some college student has actually tried something like this. Hmmm?

Re: ACPI doesn't detect lid close event until another ACPI event happens.

I can tell with the lid closed because of which lights are on.

Anyway, I don't see anything interesting at all in the logs. This is so weird.

EDIT: I'm thinking that it might be conflicting kernel modules. For example I have phc-intel and acpi-cpufreq. Plus I'm using the CK kernel. So when I get home today, I'll first try removing phc-intel, then acpi-cpufreq, then I'll try stock kernel.

Well, I don't think it's any of those things...

Does any body have a clue as to what might mess up acpi signals? Other modules or settings or something?
