Bug Description
Binary package hint: xserver-
Using Ubuntu on a HP Compaq 2230s notebook (standard install) the screen can be dimmed via Fn+Keys or xbacklight. However the screen will flicker slightly when dimmed. The effect is most visible when displaying a colorful fullscreen image. The effect could be reproduced with other Linux distributions but not with the preinstalled Windows OS.
Update: The bug can be reproduced on Hardy, Jaunty, Karmic and Lucid.

Jan, we are no longer actively working on bugs from Karmic (Ubuntu 9.10). You may check if this is still a problem on Lucid (Ubuntu 10.04) and if it is please update this bug report from Lucid with `apport-collect 581076` or simply close this and file a new bug report from Lucid with the ubuntu-bug command.
