    Hell friends
    I have installed elementary os 0.4.1 on HP 2000-2120 notebook.
    However screen is faint. I have added xgamma -gamma 0.7 to startup. But after reboot xgamma value changes automatically to 1. I am tired of re-entering value again and again. Plz someone help me.
    Thank you.

    What I recommend is creating a shell script and a .desktop file linking to the script. Then add the "application" to your startup via the System Settings. This way every time you log in the script is run and the gamma is set. It works perfectly for me. Here is an example of what I've done...

    create a new text file and add the following:

    #!/bin/bash/

    xrandr --output eDP-1 --gamma 0.85:0.85:0.85

    Note: play with the values to get the gamma to your liking. You can do this on the fly via the terminal.

    Save is gamma.sh or something like that. Note: eDP-1 refers to the monitor on my setup. To identify yours run

    xrandr -q

    Then in the terminal navigate to the folder where your gamma.sh is saved and run the below command in the terminal:

    chmod +x gamma.sh

    This will set the script as executable.

    Now you need to create a desktop file so we can add the script to your startup. Open a new text file and name it something like gamma.desktop.

    add the following to the file:

    [Desktop Entry]
    Type=Application
    Encoding=UTF-8
    Name=Gamma Setter Application
    Comment=A script to set gamma on monitor
    Exec=/path/to/gamma.sh //obviously here you want to add the true path to your file
    Icon=/path/to/icon.png //obviously here you want to add the true path to your icon file if you want one different from the base gear
    Terminal=false

    Once that is done open System Settings > Applications > Startup (I think that's what it's called) and add your gamma setter application.

    Good luck!
