Issues in saving screen brightness

  • 772

I have Ubuntu 14.04LTS and a HP Pavilion dv6500. My computer doesn't remember the amount of brightness everytime I turn it on. Can somebody help me with some terminal command lines?

Thank you.

  1. Please try this command:

    echo 2500 | sudo tee /sys/class/backlight/intel_backlight/brightness

    More info, please look in this thread How to change LCD brightness from command line (or via script)?

  2. I use xbacklight to do this, which is simple and works perfectly.

    Install it via terminal:

    sudo apt-get install xbacklight

    Then, I have a command set to run on startup:

    xbacklight -set 0

    (replacing 0 with whatever brightness level you'd like, 0 to 100)

    Hope this helps!
