My laptop didn't have brightness control working until Lucid released and now I have upgraded to Natty Narwhal still have a few flaws that reduce the using experiences. Comparing to the old versions that I installed but cannot adjust brightness this one did a lot better but still not fully solve the brightness issue of my laptop. I have a Hasee F237R Chinese made laptop. It is a cheap one but still working and I have been using Ubuntu since I bought this kit, it has been 3 years and the problems of compability with Ubuntu remains. So I would be glad if the developers of ubuntu solves these issues. The detailed info of issues I came across is around here.https://bugs.launchpad.net/ubuntu/+s...er/+bug/692421
