[Bug 756509] [NEW] N130 flickering backlight on startup

[Chris]

Public bug reported:

I have a Samsung N130 netbook and Ubuntu occasionally and erratically
flickers the backlight brightness of my screen up and down, usually on
startup and when it attempts to dim the screen on idle (even though, for
some reason, this option isn't enabled). Along with this the
notification area brightness overlay (which fades in when you adjust the
brightness) goes nuts.

The problem is stopped by using the brightness hard-keys on my netbook.

Whilst this is a beta it's not healthy for the backlight - beta or not,
OS code shouldn't be able  to damage hardware.

Description:	Ubuntu Natty (development branch)
Release:	11.04

All updates installed. Bug is present before and after update center is
run.
