Hi All! I have a Udoo Dual and LDVS 7" panel. He followed the steps indicated in UDOObuntu 2.1 but the display shows nothing. With PC connected to Udoo via serial USB cable and putty I write sudo udooscreenctl set lvds7 and reboot the system but I do not get anything to be displayed on the screen. However I have used the UDOObuntu v1.1 and it works correctly. I can't understand why one distribution works correctly for me and the other does not. Do I have to configure something else? Does anyone have this problem? Thanks! Regards!
