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.
