OK I did that. But this would seem to disable HDMI and eMMC? All I am trying to do is get LCD7 to be the default display. If I disable eMMC then I can't boot from that, and I don't have a complete ubuntu 14.04.2 July 08 with kernel 4.1 runtime image on a uSD. I don't know how to do that. Is there a performance hit using uSD as the runtime vs eMMC?
Before adding this line I was able to boot (with kernel 4.1) from eMMC while BBB was plugged into LCD7 A3. Is there a way to just disable HDMI and leave eMMC enabled? If I cut those pins between BBB and LCD7 is there a way to make LCD7 the BBB display under ubuntu? Or does kernel 4.1 accomplish the same thing by changing how those pins get used? I hope those questions were clear.
