brightness settings not applied

[myrtille]

I'm using Kubuntu Jaunty with KDE 4.2.4 and mostly the 2.6.30 kernel on an acer travelmate 6492.

When I try to change the brightness of my desktop with either the FN-keys or the powermanager-widget or the systemsettings, I can change the settings but they have no effect on the brightness. I effectively can't change it, it is always set to maximal brightness.

I can change brightness just fine when I boot into the 2.6.28-14 kernel.

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 9.04

Codename: jaunty

kernel version of the 2.6.28:
2.6.28-14-generic

2.6.30-020630rc6-generic

This is still true for Karmic and kernel 2.6.31-11. The brightness remains unchanged when I unplug or plug in the powersupply for my laptop.

The bug is still present in kernel 2.6.31-16 karmic kubuntu used with kde 4.3.2.

If nobody reacts to this comment, I will consider this bug as stale and stop updating it. It has been 6 month since I originally posted the problem and nobody has reacted to it since then.

Final I have since reinstalled, switched to 64bit, grub2 and ext4 on my system and am currently running kernel 2.6.31-21-generic and kde 4.4.2

brightness settings still can't be changed.

Finally fixed with an upgrade to kernel 2.6.35-24-generic last week.

I must have missed your request in august and i didn't check back as the situation continued unchanged.
