I've used custom userspace, but I would expect regular X to work with the patches as well. The sample rootfs probably comes with only the NVIDIA Tegra X driver installed. Have you tried installing the xf86-video-modesetting driver? That should automatically use the HDMI output if it's connected to a monitor. If not you should still be able to manually configure the outputs using xrandr. > My goal is to be able to test the hdmi audio changes on this as well > as our downstream kernel. Note that while there's some code to support HDMI audio, nobody's ever tested this upstream and it's likely not to work. So I think there may be more work required to get that running. I can help out with that, it's been on my list of things to do for a while.
