Should I configure mxcfb1 in the bootargs, or it needs some IOCTL > in /dev/fb1 to enable the device? Thanks for sharing. This works, but I'm trying to achieve exactly the opposite. I need to have my UI on the FG layer (which imho means X rendering to /dev/fb1), and my video player must render on BG layer (/dev/video16, which imho corresponds to /dev/fb0). At the moment I can't seem to be able to draw anything on /dev/fb1, so I doubt that Xorg will also run properly on it. Regards, Nikolay
