    XFCE LCD Brightness plugin missing from panel

    Greetings,

    I've run into a problem with XFCE power manager. It comes installed on Lubuntu 13.04 and per recommendations from other posts, I added the plugins as well from the repository. However, the brightness plugin still doesn't show. The FN toggles do not work for my laptop's brightness (asus ul30vt) and I need a solution to control it. Any ideas? Alternatives apps? Any help would be appreicated



    Best Regards

    The brightness setting should be stored in the file /sys/class/backlight/acpi_video0/brightness or /sys/class/backlight/intel_backlight/brightness

    Changing the number in one of these files should change the brightness.

    To set the default brightness, add an entry to /etc/rc.local, so that the bottom of the file looks like:

    Code:
    echo [x] > /sys/class/backlight/acpi_video0/brightness
    exit 0
    or

    Code:
    echo [x] > /sys/class/backlight/intel_backlight/brightness
    exit 0
    depending on which file is on your system.

    [x] is a number usually from 0 to 10, but it varies between systems.

    pqwoerituytrueiwoq is right.
    The LCD Brightness plugin is included in Xfce4-power-manager, and it allows you to control your LCD brightness level from the xfce4-panel.

    I think the op has tried installing xfce4-power-manager and xfce4-power-manager-plugins, and it still doesn't work. He said so in this thread.

    I realized my blunder after making the post. The thread was already marked as solved so I made a new topic.

    Thanks for the other replies as well. The command line does indeed work to adjust brightness. I was looking for a more graphical way (if possible). I have installed xfce power manager and the plugins. However, per the screenshot linked above, I still do not see the plugin/applet listed to add to the panel.

    Regards
