I'm a first time Linux user. Last month I installed the Hardy Heron on my new Sony Vaio laptop VGN-CR22G/W. I've had some problems with sound (internal micr not working) but the screen brightness was OK until today: After starting on battery and going to low brightness it won't go back to high brightness on power, whatever I do. Fn+F5/F6 does not respond. It all works fine when I start it up under Windows Vista. Anyone any idea how to fix this?
