        <pre>With a 4.8.17 kernel or earlier, console graphics is set (as expected) to
2560x1600 with HDMI connected to a suitable monitor.

    00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated
Graphics Controller (rev 09)

:With a 4.9.1 or later kernel, using a .config taken from a working
configuration, resolution is 1920x1200.  When it is so set, this sequence of
commands, within a terminal window in an X session, does not effect any
increase in resolution:
