I have a Jetson TX2 with Jetpack 3.1. The display stopped working, there is no output to the screen. How can I troubleshoot the issue. xrandr gives a ‘cant open display’ message.
If you have access via ssh or serial console you won’t have any problems debugging…but you do need access of some sort.
When you get access I’d start by seeing if all is ok from (especially libGLX.so):
sha1sum -c /etc/nv_tegra_release
Did you export “DISPLAY=:0” to xserver?
