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-reloadReload 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
