## Common questions

### How do I start FastAPI-DLS as a service and apply configuration?

Start it with systemctl start fastapi-dls.service and enable autostart with systemctl enable fastapi-dls.service. Then edit /etc/fastapi-dls/env as needed.

### Does using FastAPI-DLS affect NVIDIA license compliance?

Using FastAPI-DLS can circumvent NVIDIA’s license server. A Proxmox forum post warns that this may breach licensing conditions.

### Does FastAPI-DLS eliminate the low-resolution headless display issue on Tesla P4?

The source does not confirm that it removes the issue. It reports a headless Tesla P4 can remain stuck at low resolution, with limits even using grid license workarounds.

### Does the service require Uvicorn to run?

Install Uvicorn before starting the app. Without it, the FastAPI app cannot start or respond to requests.
