You can use a simple systemd service to autostart it:

1. Create a service file:

   sudo nano /etc/systemd/system/mycompton.service 

2. Add the following configurations:

   [Unit] Description=compton autostart script After=network.target [Service] Type=forking ExecStart=/usr/bin/compton -b --vsync opengl Restart=always [Install] WantedBy=multi-user.target 

3. Start and enable the compton service:

   sudo systemctl start mycompton sudo systemctl enable mycompton 

4. Check the status:

   systemctl status mycompton 

5. Stop it with:

   sudo systemctl stop mycompton 

Note:

Replace the line /usr/bin/coompton with the result of which compton, if different from my own entry.
