I succesfully install it on XU3, and make many test from last 2 days.
But when I turn on 15 minutes ago, I see this screen :
I try to change video mode on my screen, reinstall batecera, change HDMI input, etc.. but I've no change.
I don't try to change HDMI cable, because I haven't an other from now.
Is it a know bug ? Or what ?
