    Map Fn keys to change brightness

    I have installed Fedora 12 (GNOME) on a VGN-AR41L. I have found that in /sys/class/backlight/nv_backlight I can change the brightness of the backlight. I want to assign the Fn+F5 to decrease the brightness and Fn+F6 to increase. These combinations are recognised from my system as XF86MonBrightnessDown and XF86MonBrightnessUp respectively. Any help?

    There is this, but I don't know if it works with a recent version of Fedora.

    Regarding the above, see comment at the bottom of the following page:

    Maybe the following will work. I copied this from a French mailing list for a different model Sony.
    Use sonyacpi and then type "sudo-s" then "echo" 8 "> / proc / acpi / sony / brightness" to maximum brightness and "echo" 1 "> / proc / acpi / sony / brightness "for a minimum brightness.
    Instead of sudo, I would just use su - to log in as root in terminal.
    Fedora 19 Gnome on a ThinkPad X220, i5-2540M CPU, Intel HD Graphics 3000, Intel N 6205 wireless, and Sierra Wireless 754S Mobile Hotspot (AT&T)
