[meta-freescale] imx6q: Xorg multi screen support

[randy.krakora at freescale.com]

Is there any updates here?

I'm trying to accomplish the exact same thing and getting the same error ( VGA Arbiter error ).

Thanks,
Randy Krakora

I didn't test multi-output Xorg in MX6.

So it may need some debug. Did you researched in community.freescale.com<http://community.freescale.com>?
