Ich durchforste gerade den syslog meines immer man wieder instabilen Systems und entdecke dabei:
Code

Jun Komisch daran ist, dass es die Datei nvidia-persistenced.service weder in /etc/systemd/system (als Link), noch in /lib/systemd/system gibt.
Warum wird dann überhaupt versucht, den Service zu starten?
AH: gefunden: Die Ursache liegt in /lib/udev/rules.d/71-nvidia.rules. Es fehlt also wirklich nur der .service File
