I have a Sony Vaio notebook (VGN-SR) which came with Windows Vista, which I un-installed and replaced with Ubuntu Linux 9.04. Under Windows I had the ability to adjust the screen brightness, volume, etc, by holding down the function modifier key (labled “fn” and located between the control and window keys) and pressing the corresponding function key (i.e. F3, F4, F5, etc).
The computer also came with a few built in keys called “mode, “settings,” as well as five other keys with no labels. They did something under Windows Vista, but now don't do a thing. The computer also came with a built in web cam. Any idea how to get all of this working under Linux?
