Agreed, but then you have to debug where this event comes from and why your
system seems to be the only one doing that. At least I have yet to receive a
report for such a behaviour.

Do you have any other software running that might be handling the button, like e.g. a graphical desktop environment?

Does the problem still appear with the latest version of acpi-support?

Yeah, that was needed when we had all this logic in acpi-support, but a lot of
it has been moved out of it. So this test wouldn't work anymore I'm afraid.

The example name should be powerbtn.sh or somesuch I agree, but that doesn't
exactly prove my point mood, or does it?
