Nvbuf_utils warnings

We use our jetson in headless mode, without an X server. Whenever we run a program that uses nvbuf_utils.so, we get the line:

nvbuf_utils: Could not get EGL display connection

Is there a way to clean this output (we use stdout for our logging)? Is nvbuf_utils using a global object that tries to use the EGL display?

In headless mode, please make sure you keep nvdisplay driver enabled. Please refer to
