Thanks, pomsky I have found a way to make it after doing these steps

  1. Create a new text file, say set-xgamma.sh somewhere

  2. add the following lines to the file:

    #!/bin/bash
sleep 7 
xgamma -gamma 0.70

    and save the file.

  3. Make the script executable.

  4. use this command crontab -e
  5. put @reboot sh $HOME/set-gamma.sh & there with your file path
  6. save it by clicking ctrl+o then ctrl+x to exit and it works :)

  1. Create a shell script for the command. Create a new text file, say set-xgamma.sh somewhere and add the following lines to the file:

    #!/bin/bash
xgamma -gamma 0.70

    and save the file.

  2. Make the script executable (refer to this).
  3. In Startup Applications, while editing the program, click Browse... next to the 'Command' textbox and select the set-xgamma.sh file you just created.
