Hello Everybody,
This is my first post in the mailing list.
I have Acer Aspire 4741Z laptop. After installing Ubuntu 10.4 everything is
working out of the box. Only problem is I am not able to adjust screen
brightness using Fn + left/right arrow keys. When I press those keys slider
moves, but screen brightness does not changes. As brightness is always at
maximum it drains battery fast. I have updated my distro with all latest
patches and updates including latest kernel patch. But still have the
I even posted this problem on ubuntu forums also, but no luck there.
Searched ubuntu forums also but found nothing.
Is anyone else having same problem?
Thanks in advance.

Amit Gokhale.
