When it's booting the system, I can change the brightness by special keys normally. When Ubuntu is working, the keys usually work for about the first minute, and later they just stop functioning correctly - when I press them, there is only brightness icon shown and nothing else happens. I also noticed that it recognizes when I' ve closed the laptop if and only if the brightness control is working. Can anyone help me? cheers gosciu

That's where the Ubuntu experts will more likely be watching. __________________ Sometimes, real fast is almost as good as real time.
