This is not a Fedora specific problem, I've noticed it on several other recent distributions as well, so it is likely a plumbing problem. Still, I'd appreciate some help diagnosing it so that I can file a useful bug and point at the right package (e.g., is it kernel, acpi, upower).
Description of problem: At some point in the last year my computer has lost the ability to dim the screen when going from ac -> battery, or to bring brightness back up to full brightness when going from battery to ac power. I am able to dim the screen using my Fn keys, and I can even use gnome's dim when idle on battery (though I've changed this to a more reasonable time - from 10 seconds to 500). I've aso tried tricking the system into doing this by changing the idle time to 0, and even -1, but it seems gnome considers this trickery unacceptable and simply doesn't dim at all when idle.
Currently using Fedora 17, but same problem exists on my Fedora 16 partition. Advise and tips appreciated
