Comment 7 for bug 910040

Hi there! Unfortunately it has not been implemented in Ubuntu 12.04 and the PPA is not up to date.
On the other hand, just install the package for Natty and it works for Ubuntu 11.10 and 12.04. I have been using it since one year and I had no problem. I attached to this comment. Just install it, restart the system and you can test it. To test it, just let fall your computer, obviously over your bed or shake it up and down and the LED of the hard disk should change to amber when is parked. Another way to test it, is that change the Power settings so when you close the lid of the laptop, it turn of the screen and avoid suspending. When the lid is closed, the deamon is even more sensitive and it parks the hard disk with even less movements. Then close the lid and move your computer and the LED should change color amber.
