The command autorandr stands for automatic screen layout manager for X. It is a utility tool used in Linux systems to automatically set up and manage different screen layouts and display configurations.

When you connect or disconnect an external monitor or change display settings, the autorandr command is used to detect these changes and automatically adjust the screen layout according to predefined configurations.

By using autorandr, you can create and store different display configurations, such as single monitor mode, extended desktop mode, or mirroring mode. Once the configurations are set up, autorandr will recognize changes in the display setup and automatically apply the appropriate configuration.

This command is particularly useful for laptop users who frequently switch between using their built-in screen and external monitors or projectors. It saves the hassle of manually adjusting the display settings every time a switch occurs, providing a seamless and convenient experience.
