then run:
systemctl disable sensorfwd.service
ps -ef | grep sensor and kill the pid
/usr/sbin/sensorfwd -c=/etc/sensorfw/primaryuse.conf --log-level=warning --no-magnetometer-bg-calibration &
as root... (best to change log level to debug so you can see it working)
change orientation with debug, and you should see this in terminal output
I added my own systemd service that runs a script
/etc/systemd/system/multi-user.target.wants/ath6kl.service
[Unit]
Description=ATH6KL
Before=network.target

[Service]
RemainAfterExit=true
ExecStart=/usr/bin/enable_sensors

[Install]
WantedBy=multi-user.target



I can't get it to run with systemd with the service they are using... maybe over DBus
/usr/bin/enable_sensors (executable)
#!/bin/bash
/usr/sbin/sensorfwd -c=/etc/sensorfw/primaryuse.conf --log-level=warning --no-magnetometer-bg-calibration &
