Can't adjust brightness on Acer Aspire 5738 running Karmic
Can't adjust brightness on Acer Aspire 5738 running Karmic. The same happened under Jaunty. The screen never seems to reach its full brightness and it flickers.
The notify osd shows a bright bar indicating the screen brightness increasing or decreasing when I use the fn key + the corresponding keys for increasing or reducing the screen brightness, but the screen always stays the same.
I can move the arrow in the brightness applet in the Gnome panel up and down, but nothing happens, either.
I think I'll report a bug.
