Autostart on boot

[metal450]

What method did you use to get this to run on system startup? It works when I launch it manually with sudo, but if I try to start it with systemd, it gives XOpenDisplay failure!.

I tried starting it like:

[Unit]
Description=AccuPoint driver

[Service]
Type=oneshot
ExecStart=/opt/accupoint-driver

[Install]
WantedBy=multi-user.target

(after copying mmm to /opt/accupoint-driver)

[metal450]

Also using sudo crontab -e with @reboot /opt/accupoint-driver desn't seem to work :/
