Hi,

Commit cfecde 'drm/i915: Don't enable pipe/plane/VCO early (wait for
DPMS on)' causes the external VGA connector to stay off on boot. The
display powers up when X is started. I'm guessing an explicit DPMS ON
is not done on boot.

Reverting this commit fixes the issue.

Regards,
David.

It gets worse: my primary (and only) display is VGA, and my monitor
reports that it has been configured to an invalid mode.  The result is
no usable display.

Likewise.
