    Exclamation F11: Brightness Problem

    Since i upgraded F10 to F11 the Birghtness-Applett doesn work. In F10 i configured the Fn-Shortcuts to set the brightness with backlight. This doesńt work any more.

    00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev e2)
    00:1f.0 ISA bridge: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge (rev 02)
    00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7 Family) SATA IDE Controller (rev 02)

    I have a Samsung NC10.

    Some body an idea?

    Disable Kernel Mode Setting by adding the following kernel boot parameter:-

    You may also want to add the following kernel boot parameter as well if you want to see the animated Plymouth startup screen:-

    EDIT: Just for some background here's a bug report on bugs.freedesktop.org bug 20963, and two regarding the NC10 and backlight control on the Redhat Bugzilla which are bug 496975 and bug 502516.

    It appears that you can control the backlight without disabling KMS by running:-

    setpci -s 00:02.1 F4.B=XX

    where XX ranges from 00 to FF. Though I haven't tried it myself as I don't have Fedora on my NC10 at the moment.
    EDIT: Tried the setpci method and it works fine on my NC10, this is without any other changes.
