How to change screen brightness (on laptop)

1st Official Post

    I have a pretty slow laptop (N3050, 2GB RAM, 32GB eMMC), and since it's not good for anything else, I installed LibreELEC and use it attached to my TV. However the laptop has good battery life (around 8 hours) so I would like to use it as a portable media player. Audio, video works great, however the screen brightness is pinned at 100%. Is there any way to change screen brightness?

    If you have the laptop connected to the TV (permanently?), then you should be able to disable the laptop's screen and only use the TV. Every laptop has keyboard combinations for that. Actual screen dimming during videos is not supported by Kodi itself. Meaning, perhaps something can be done via the Linux command line using the startup.sh file.

    An example with the VGA1 output screen:

    Code
    xrandr | grep " connected" | cut -f1 -d " "

    Output:

    VGA1

    Code
    xrandr --output VGA1 --brightness 0.7

    And hopefully it works. I would try things out first directly typing on the command line.

    Yes, when I connect it to the TV, I blank the laptops screen. What I meant is to use the laptop standalone, watching videos on it's screen, not connected to anything. Will try your line of code.
