Re: laptop brightness in gnome
In your session startup, run
xrandr --output LVDS --set BACKLIGHT_CONTROL legacy
good luck, and before you run in startup, test it in a terminal
It might not solve the problem, but it solved many of my own backlight problems.

Re: laptop brightness in gnome
I remember I had this problem too, and I solved it, but I use KDE now so I cant remember! Try adding the brightness applet to the taskbar. I've heard that worked for some people. There are also brightness settings in the display options aren't there?

Re: laptop brightness in gnome
You don't happen to have enabled the "dim screen when inactive" option gnome-power-manager?

Re: laptop brightness in gnome
I had the same issue, but my memory fails me too, its one of these for sure:
1) use xscreensaver instead of gnome-screensaver, or none at all
2) play around with xset settings in terminal
3) use gconf-editor and look for some keys relating to gnome-power-manager and screensaver, switch em around
