I also own a T2010 - I am using Intrepid Beta. Observations... * Fn (F6&F7) keys bring up onscreen applet and change the values but the brightness doesn't change. * related - the values change two steps at a time - both up and down. * xbacklight can be called directly using get & set, but again no change in brightness. * unplugging AC causes onscreen applet to pop up showing change to half value - no change in brightness. Resets to full when plugging AC back in. * observing /proc/acpi/video/GFX0/LCD/brightness I can see the values changing when using any of the above methods.
It appears the mechanisms for changing the brightness work - but the brightness itself does not change. I was using Hardy previously and the brightness changed when using xbacklight or un/plugging the AC power - so this is a regression. The onscreen applet and Fn keys previously did not work - so there has been an improvement in 'functionality' but it would be nice if the brightness actually adjusted. This will of course have a reasonable impact on battery life if not fixed. I am happy to provide more info or run tests if required.
