[arch-general] Weird acpid issue

Hello, My laptop has ACPI running to detect, among other things, the lid state, so that it can shut off the screen if it is closed. However, every once in a while, the functionality simply doesn't work -- I close the lid and the computer doesn't respond. Running /etc/rc.d/acpid restart makes it work again, only to fail again in a few days. I am running ACPI 1.2 on 2.6.28. Any ideas? -- Thanks, Leonid Grinberg lgrinberg@gmail.com
