I'm using Ubuntu 11.04 on Dell Inspiron 1464 which has onboard graphics.
I too had the same problem and I wrote a script to overcome this issue.
Thought it would good to share it with the community.

Just upgraded to the Karmic Beta - and the whole screen brightness alternates
(low/high) every 1/2 second until the power applet kicks in and is displayed.
Once the Gnome power manager 2.28.0 applet starts - the display is fine, and it
stablises. This wasn't the case in 9.1 Jaunty.

Great to hear! Thanks for testing. Unfortunately, we can't bring this
into previous versions of Ubuntu. The Stable Release Update [1] and
backporting policy [2] generally only allows security bugs or bugs that
could cause severe loss of data. Thanks again for helping make Ubuntu
better!

That's alright Scott, I figured that would be the case– policies are in
place for a reason. I'm just glad to know that it IS fixed! If the
changes aren't too huge, I'd be willing to test a patch file if you've
got one, I'm sure people subscribed to this would appreciate it. What do
you think?

There has been a pretty significant change in how GPM and power
management in general works between Jaunty and Karmic, a patch won't
easily work (dependencies have changed significantly, HAL has been
deprecated in favor of devicekit-power). Fixing bugs in power
management has been a moving target
Whoa, HAL's gone? I need to keep up-to-date! I am glad to hear it's
stabilizing, though :) . Meh, I only have a couple of months to wait for
Karmic, right? Keep up the good work.

@Timo
Yes, the idea now is that it adjusts by a value set in the GConf keys
not to a fixed value. So it is a -30% on unplug and +30% on plug in.
This also is intended to fix some problems users have with external
programs setting the brightness outside of GPM (sadly).
@ali_deren
Unfortunately
Just installed hardy on my acer 5920 laptop. This issue seems to be
fixed there for me. The screen 'flickers' when i adjust the brightness,
but the levels are set correctly, and they stay that way. I'm happy! :)

Ted, I tried it and now the brightness is dropped when the system is
left idle, but when I resume work it drops to minimum :)
Also, AC plugged in the settings have no meaning, ie. it doesn't set the
brightness to the level that's on the capplet, but maybe 30% more than
what it used to be on
Ted, unfortunately It didn't work on my notebook. :(
It still increases and decreases automatically and continuously..
