LCD Brightness Cannot Be Adjust on Laptop using Fn / Function Keys

Bug #204101 reported by Ryan Sinn on 2008-03-20
Affects Status Importance Assigned to Milestone

Bug Description

Function Keys no longer adjust brightness since kernel 2.6.22-11 I'm not sure if it's specifically related to that, but that's when I noticed it.

I am running hardy, all patched up as of 2008/03/19 20:26 CST -- and haven't been able to adjust or control the brightness of my laptop LCD for approximately 2 weeks.

Pressing the up and down brightness keys do bring up the OSD, but the actual brightness doesn't change.

I looked at the other dozen bug reports currently open regarding this issue and they all relate to older releases of Ubuntu.

I am running an ThinkPad X61T with Ubuntu 8.04
