    Question How to turn backlight keyboard on?


    I am wonder if there is a way to turn on the backlight keyboard on by editing a file or by running a script.
    I have a Toshiba M640 with Hybrid Graphic Card Intel/NVidia (upgrade to NVidia was a requeriment to have the backlight keyboard) but I cannot turn it on.
    I have an option in the BIOS to turn it on, but as soon as Ubuntu starts loading it turns off.
    Any ideas?

    I have the same problem on a Toshiba Satellite A660. Same as OP - lights up during POST, tried setting it to always-on in BIOS, tried Fn-Z. Any ideas? I looked at but the folders aren't the same, naturally. Looked through /sys/, but couldn't find anything that works.
