laptop program "acme" doesn't work for brightness

[nocturnus_gr]

When i used Suse 9.1 acme worked fine for my laptop. Well, i don't remember if i had configured anything having to do with brightness then, but anyway it worked fine. No i downloaded the file "acme-2.4.2-2.1.fc2.dag.i386.rpm" for my laptop, but neither the keys of my laptop, which have to do with brightness respond nor can i find any configurations options in acme for "brightness".
What can i do?

To make it more clear, other ideas about programs or ways that adjust brightness would be also helpful.

Determine who the developer or team that created acme is and ask them - that usually works pretty well. (Google is your friend...)
