Question Detecting current ACPI level in Fedora 9


I just got a new 47 inch (LG) TV (as a monitor). It does not go into a low power mode when the Fedora 9 box kicks the display into power save. I've been writing some scrips to control this via the RS232 port, but how do I check to see what power mode the system is in? Or better add my script in so that it will run immediately when that change happens.

When acpi LKMs get loaded in the kernel a read only interface is available: one of the keys in /proc/acpi should hold the C-states. If low power mode kicking in isn't noticable via /proc/acpi/events I doubt 'acpid' can help you to run your script automagically.
