This didn't work for me I wrote all the scripts, put in the right place, check "Allow executing file as program" and nothing
I must change last line on this "/sbin/shutdown -h now" , becouse when there was "Rebooted via gdm." I can't close the system. It only logoff user and back to GDM screen.
So I don't now what I'm doing wrong, but I still doesn't have this sound
