I'm not a kernel developer, but I have a problem that needs addressing, and I fear that might mean me. Any guidance would be appreciated. I've got an HP Pavilion dv4000 notebook. I'm running Ubuntu Feisty (pre-release), with this kernel: "Linux peace 2.6.20-12-generic #2 SMP Sun Mar 18 03:07:14 UTC 2007 i686 GNU/Linux" My problem is this: Whenever I run this command: cat /proc/acpi/button/lid/LID0/state I always get the result: state: open This happens even if I'm pressing down the lid button when I execute the 'cat' command. I believe this is the root cause of why none of the normal ACPI goodness happens when I close the lid (aside from the LCD back-light turning off, but I don't think ACPI is involved in that.) Does anyone know how I can debug this, or at least what information I (as a non-kernel developer) can gather to help out the folks that try to make this stuff work?
