The xf86modesetting driver should work with any kms driver (though it's been some time since I last tested it with imx-drm) You won't need fbdev, but without it the kernel does not activate the display during boot, so it will just stay dark until X starts. > > Is there a good overview of things, particularly wrt. imx6? Not that I know of, at least there's no i.MX specific drm documentation.
