Comment 13 for bug 385683

I am having the exact same problem as Michał Kaczmarek (above) on my Samsung R60+ laptop. Whenever I change the monitor brightness using the Fn key + up or down, there is no key release generated, which causes most of the OS functions to hang as it thinks there is a key being held down. However as I am new to Ubuntu I am not fully aware of how to apply the above patch - could someone help? Thanks
