[Launchpad Bug Tracker <882434@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

It is not possible to change the brightness on my Samsung p560 Laptop.
The OSD shows up when using the brightness keys, but the brightness is not changed. I am not sure which package this problem is in. I can only change the brightness before booting ubuntu.

I have the Intel GMA4500 gpu, and this has been an issue since around 9.04. 
There is some information in this bugreport: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/338182, which describes a different issue. 
And an old bugreport set as wont fix: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/338173
Sadly any nvidia tools will not help.

I currently have a clean install of:

Distributor ID:	Ubuntu
Description:	Ubuntu 11.10
Release:	11.10
Codename:	oneiric

Kernel: 3.0.0-12-generic-pae #20-Ubuntu SMP Fri Oct 7 16:37:17 UTC 2011
