I have a SONY Vaio laptop and here are two questions:

- my old computer's CRT had a dial to control brightness. I haven't found any on this computer, nor a way to modify brightness digitally. Is there a way to do this?

- How can I change the basic background color on the screen? Everything is coming out white nowadays. I had changed things around after eye surgery and now that my eye is improved I changed things back. Now nothing I do seems to change the background color. I'd like something a bit softer than "brite white."

Thanks for whatever help you can offer.
