I have Ubuntu 8.04 32 bit all updates and having same issue on my laptop. My function keys "change" the brightness but not really. If i turn the brightness all the way down, the screen goes nearly black, as soon as i put brightness at the lowest level it comes to a VERY dim state, and further increasing of the brightness thru the 'F' keys does nothing.
