Steven,
I don’t have any problem with screen brightness or such - I just want to say that your screen brightness adjustment how-to was really quite well done. I have written a lot of how-tos over the years, and my goal is to come up with something as clear and inclusive as what you did here. I have cut/pasted your post into a file and put it in my linux_tips directory. I am sure it will come in handy some day… thanks!
