[Intel-gfx] ZaphodHeads with intel X driver

[Kamble, Nitin A]

Sorry Chris, I spoke too soon.
  The working config was single screen/monitor config, as attached here. Commenting of SNA line made it work.

The dual screen configuration is still failing as before. And if I comment out the SNA lines I get this in the X log.
