How to save backlight settings in Ubuntu

In Ubuntu 12.10 (and many other versions) back-light setting changes we do are not retained after a restart or a resume; back-light is always set to maximum, which is very irritating.

To save the backlight to a specific value we can use xbacklight.

We can specify a percentage (I prefer 73%) as following:
xbacklight -set 73
We have to add this as a 'Startup Application' in order to apply the brightness change at the Ubuntu login.
