[ubuntu-uk] Computer restarts on shutdown

[James Morrissey]

Thanks for this Tyler.

At the moment i only seem able to find the acpi call for the power button,
not for the cog.

Are they the same at:

/etc/acpi/events/powerbtn

and then:

/etc/acpi/powerbtn.sh

?

If not can someone tell me where the acpi script for the cog is?

Thanks,

j
