Well, I thought about it, and you're right... What I really need is to be able to do something upon an acpi event, like running a script when I close my lid... But I didn't find these info anywhere =( Please help me! =) acpi is working, it has control on my fan and monitors my CPU temperature. I tried devd -dD, and it reacts when I close my lid, but I don't know how to use this output...
