    It's a pity that doesn't influence battery usage... :\

    Btw, first time I play with Debian packaging so I may have screwed the dependencies.... but it seems to work on my old Sony
    (And since I have no clue how to install a service/config files on it via deb, it's not part of it either...)

    Thanks mate... it is working perfect on my Sony Vaio FS630.

    First, make sure that the sony-laptop module is loaded. The easiest way to do this is to type:

    sudo modprobe sony-laptop
    (this loads the module if it wasn't loaded, or it should return an error if it is)

    Now, Issue the next command, its the same command as before, it just uses a different directory. "your_user" is whatever account you need to use to control brightness.

    sudo chown your_user /sys/class/backlight/sony/brightness

    Finally use the next command to set it the lowest level brightness level. To change it to other levels, simply change the number to anything between 1 and 8:

    echo 1 > /sys/class/backlight/sony/brightness

    Hope this helps.
    Thanks this worked for me Sony Vaio VGN CR14GN

    What if module "sony-laptop" cannot be found? That's strange.

    On Kubuntu Gutsy that is.

    Re: HOWTO: Adjust brightness on Sony Vaio

    hi all,
    i tried this fix on my VGN NR260E, but no success.
    there is no /sys/class/backlight/sony/brightness in my machine, but i have /sys/class/backlight/acpi_video0/brightness.
    i did

    echo 1 > /sys/class/backlight/acpi_video0/brightness

    but from what i can tell, nothing has changed.
    here's hoping that future versions of ubuntu fixes this important problem!
    (i have used gutsy 7.10, and now upgraded to hardy heron, but no luck so far).

    thanks for any suggestions though!

    Re: HOWTO: Adjust brightness on Sony Vaio

    I am almost giving up from 8.04 (hardy heron).

    I tried everything to make the brightness control works on my Vaio VGN-FZ430E. Nothing works.


    Theres no sony_acpi modeul, no /proc/whatever/sony ... the LCD brightness control in gnome panel, doesn't work.

    Does any have a last clue, before I get to vista (unfortunately I need the battery) or get blind.. lol.

    Thanks mates!

    This did`nt work for me.
    I have a Sony VAIO CR31 with ubuntu 8.04.
    I adjusted the backlight /brightness by writing

    sudo nano /sys/class/backlight/sony/brightness

    change the number between 1-7 and save the file.

    This worked great for me
