The page also says:<br>
<br>
"In this page, we limit ourselves to a Linux-based system. On Windows<br>
and macOS, offscreen support is available, but true headless operation<br>
is currently not widely used and hence left out of this discussion."<br>
<br>
Thus, the page is mostly for Linux where people have options of using X or not.<br>
