The application does not start after using the function save current settings #222

Describe the bug In the screen manager application, I turn on both screens. Then I launch the brightness-controller app. Adjusts the image for both screens and saves the configuration: save current settings function. Then I turn off one screen programmatically and start the brightness-controller application again. The application does not start. An attempt to run in the command line gives the message:

xrandr: Need crtc to set gamma on.
