Screen brightness not working on Toshiba NB550D netbook

[James Davenport]

I have performed a clean install of Ubuntu 12.04. On the netbook the Fn + F6 and Fn + F7 key control the brightness. When pressed the on screen popup is shown (showing the brightness level) and this changes in line with key presses.

Though the screen brightness remains the same which is the highest brightness level.

Also the brightness level does not change when using the System Settings > Brightness & Lock screen.

The impact of this bug is that I will need to rollback to 11.10 as this reduce the battery run-time to 50%.
