Hi,

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 problem.
Is anyone else having same problem?
Thanks in advance.
