Talk:Automatically reduce brightness

how to use thinkpad-acpi to automatically reduce brightness ?

The article says the provided info is now deprecated in favor of thinkpad-acpi and says to refer to the thinkpad-acpi pagr which doesn't contain any information about how to automatically do it. I followed the links and look at the mailing list but couldn't find any useful information on that mattter, if anyone actually has automatic dimming working using thinkpad-acpi, it would be nice to share it here.
