/etc/init.d/performance_governors.sh

First, remove the init.d script registration: sudo update-rc.d performance_governors.sh remove

Create a systemd service file: sudo nano /etc/systemd/system/performance_governors.service

Add this content:

[Unit]
Description=Set CPU and GPU governor to performance
After=multi-user.target
[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/etc/init.d/performance_governors.sh start
ExecStop=/etc/init.d/performance_governors.sh stop
[Install]
WantedBy=multi-user.target
Reload systemd to recognize the new service:
sudo systemctl daemon-reload

Reload systemd to recognize the new service: sudo systemctl daemon-reload

Enable and start the service: sudo systemctl enable performance_governors sudo systemctl start performance_governors

Check the status: sudo systemctl status performance_governors
