Jetson nano 2gb error ethernet issues and X11 server connection

[yunuscurrie]

Hi I have 2 issues that I would like to address. I am using a jetson nano 2gb running jetpack and ubuntu 18.04.

My first issue is that despite connected to ethernet, I have no wifi. It shows that it is connected. I have solved this issue as a temporary fix but I dont remember how I did it and I would like a permanent one.

The other and more pressing issue is whenever I try and display my live camera feed by running in the ubuntu terminal: video-viewer /dev/video0, making sure that /dev/video0 is correct, i get the following errors:

Invalid MIT-MAGIC-COOKIE-1 keynvbuf_utils: Could not get EGL display connection
MIT-MAGIC-COOKIE-1 key[OpenGL] failed to open X11 server connection.
[OpenGL] failed to create X11 Window.

Not sure what have you done on your device, can you try to flash SW on device to see if can work?

hello yunuscurrie,

@yunuscurrie

Could not get EGL display connection

had you try configure your display environment with… $ export DISPLAY=:0
you may also running with $ xrandr utility to examine your display settings.
