Comment 57 for bug 12637

I have a Lenovo 3000 C200 and the same issue since the upgrade to Hardy (32bit). I was previously running Ubuntu 7.10 (32bit) with kernel 2.6.22-14rt flawlessly. All the new kernel options in 8.04 show this behavior in my laptop. Even the manufacturer bootup screen looks dimmed. The Fn keys work ok so I adjust the brightness every time I boot but it's really bugging me. :(
