How to prevent resume from sleep/suspend on lid open?

Question

I've got pretty much the same problem as this old 2006 thread on the Ubuntu forums: my old laptop's lid is a bit shaky, which causes the computer to wakeup/suspend if I just touch it the wrong way (e.g. lifting it up to move it).

Back then, the fix (see link) was to have a startup script disable LID in /proc/acpi/wakeup every time the computer boots. I'm wondering if there's a better, less hacky, solution?

Did they get rid /proc/acpi/wakeup in Maverick? It still exists on my Lucid system, and I don't see why it shouldn't work. — Ryan C. Thompson, Oct 26 '10 at 00:52
Nope it's still here, so the solution from 2006 still works. It's just a bit of a hassle to maintain. — Ludovic Chabant, Dec 16 '10 at 06:50

Its no less hacky, but you can simplify the solution by adding echo "LID " > /proc/acpi/wakeup to the /etc/rc.local file. This way you don't have to create a startup script.

What about changing it to Blank screen when laptop lid is closed. This is way you will not get suspended.

Nope... this keeps the laptop running when I close the lid, but if I suspend it manually before that, it still wakes up when I open the lid. The idea is to prevent the laptop from waking up when the lid moves a bit, not preventing it from going to sleep. – Ludovic Chabant Oct 19 '10 at 04:38
