This stopped working when I upgraded to Ubuntu Intrepid. Even more strangely while the scripts are still installed, even they are never called.

It appears that thanks to moving towards HAL (which is probably a “Good Thing”) these scripts are no longer used. The scripts which are used can be found in /etc/pm/. Not only has the location changed, but the script format has too.

Previously, my script was found in /etc/acpi/resume.d/99-custom.sh looked like the following,

#! /bin/sh
# Turn off the CD drive and the bluetooth device
echo 1 > /sys/devices/platform/sony-laptop/cdpower
echo 0 > /sys/devices/platform/sony-laptop/cdpower
 
echo 1 > /sys/devices/platform/sony-laptop/bluetoothpower
echo 0 > /sys/devices/platform/sony-laptop/bluetoothpower

Now my script script must be found in /etc/pm/sleep.d/10-custom and looks like the following,

#!/bin/sh -e
case "$1" in
	resume)
		# Turn off the CD drive and the bluetooth device
		echo 1 > /sys/devices/platform/sony-laptop/cdpower
		echo 0 > /sys/devices/platform/sony-laptop/cdpower
 
		echo 1 > /sys/devices/platform/sony-laptop/bluetoothpower
		echo 0 > /sys/devices/platform/sony-laptop/bluetoothpower
	;;
esac

The main reason I’m posting this on my blog is that this change does not seem to be documented anywhere. Searching on Google for things like “resume script intrepid” or “/etc/acpi/resume.d intrepid” does not come up with anything useful. Hopefully some people will find this helpful.
