If you physically disconnect the monitor and run headful, then on X, the XR&R
extension will return NULL from querying the display config.
In such a case we can't say we are headless since X is present and operational, and we are way past the point of deciding we are headless. Plus this disconnection could happen at any time. In this case just return a default mode based on the
X window root properties.

A regression test is not provided because this is covered by JCK tests
and is configuration specific.
