  1. using SDKManager to install Jetson Linux 35.6 , the image was successfully installed, but only startup screen showed up with some logs, then the monitor went dark and lost signal. I managed to use debug port to log the errors, as shown in debug.txt
  2. I tried to manually flash the system to 32.7.5, which comes with ubuntu18.04, everythings works fine, I got display, but when I restart the device, login the system, I got this error

  1. Are you able to get the log from 32.7.5?

  2. Jetson is not able to support add mode from xorg config. The mode has to be from EDID of your monitor.

  3. What change did you make on this board in comparison with NV devkit?
