    Re: Sony Vaio VPCCW1E1R Brightness control Ubuntu 9.10

    Hi, I'm having the same problem on a brand new Sony Vaio VCPF1 with a nvidia
    310M (218GT). No Fn keys working, ubuntu lucid detects the keys but there
    is no brightness change.
    Is there a way to revert the changes in case the steps in
    this post doesn't work?
    I recovered brightness control adding a line to xorg.conf and using brightness applet, after some weird
    illumination effects, now it works fine.
    (great tip!)
    Otherwise the nvidia driver will set it to 100%.
    Thanks in advance and great post.
    Seba
