system76-power is a utility for managing graphics and power profiles. When run in daemon mode, system76-power manages the fan speed of fans connected to the System76 Io board on Thelio desktops. To start the daemon at boot, add the following to your /etc/rc.d/rc.local script and make sure rc.system76-power has executable permissions set: if [ -x /etc/rc.d/rc.system76-power ]; then /etc/rc.d/rc.system76-power start fi The system76-power daemon log messages are logged to /var/log/system76-power.log by default. Logging can be disabled by setting LOG_FILE=/dev/null in /etc/rc.d/rc.system76-power.
