When I ran Debian, the shutdown process would never power off my machine. The processor fan would stop and the screen would read “Power down”, leaving me to press the button. A minor irritant.

I had the same problem with Ubuntu, until yesterday evening. After reading a few forum posts which all seemed very involved and a bit disjointed, I added:

apm power_off=1

to /etc/modules

Now, Ubuntu powers down automatically. Hooray.
