Bug Description
When the login screen (gdm) appears the screen of my MSI Wind U100 netbook starts to flicker, i.e. the backlight brightness alternates. The brightness widget is also shown and its bar goes up and down for 1 step.
When changing the brightness manually using Fn-F4 and Fn-F5 during the login screen it keeps on flickering but at a different brightness offset then.
After logging in the flickering continues until vigorously changing the brightness manually using Fn-F4 and Fn-F5.
After logging out and returning to the login screen it again starts to flicker.
My system is running latest Ubuntu Karmic (development branch), release 9.10.
I just found bug report 415023 which sounds very similar. But changing the brightness fast does not induce the problem for me again. Also, it does not stop flickering for me after ~30 seconds like the other report says.

The brightness toggles up (brighter) and down (dimmer) by what appears to be one click of the Fn+F4 and Fn+5 keys. The flickering continues through the GDM login screen and still exists after the desktop is displayed. Using the Karmic Netbook Remix build from 2009-09-16, this item still exists (system is also MSI Wind U100 netbook). The flickering eventually stops, but I would not say that is stop at a consistent rate.
