[Bug 581076] [NEW] HP Compaq 2230s laptop: Screen flickers when screen brightness dimmed

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

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.
