Jetson Nano B01, no graphical environment

Hello,

I have no graphical environment. When I set-up my Jetson Nano B01 it was purely in text mode. I have tried to start gnome, see below, but with no success.

~# sudo gnome-terminal
Unable to init server: Could not connect: Connection refused

Failed to parse arguments: Cannot open display:

Any assistance with a way forward would be appreciated.

James

This is jetson tx2 forum.

Woops, sorry. Will you be able to recatorgize this and help me out?

James

Done.

Please describe how you flash your jetson nano.

I’m using Ubuntu 20.04 on a Lenovo T420 laptop. I downloaded the Jetson Nano file using the link on the Nvidia Jetson Nano set-up page. I flashed the file to a 64gb sd microcard using Etcher.

I own two B01s and have had the same experience with both.

Refreshed twice on two separate B01s with no luck. Any more ideas would be appreciated.

  1. I am curious about why sometimes users hit this issue. Could you dump your /var/log/Xorg.0.log here?

  2. A quick way to resolve this is use sdkmanager to flash the whole board.

NVIDIA SDK Manager | NVIDIA Developer

Thanks for your email. I will send you the log later today.

The requested log is below. In the mean-time I will try the SDKManager. Thanks for your continued help. Btw, I did try an HDMI monitor (plus USB keyboard and mouse) but there is no HDMI output.

Is that the full log?

Could you also check command “ps aux |grep gdm” and share your result?

The requested output is below. I went to check the Xlog file but it is gone! Also, I tried SDK Manager but I get a message that it does not work with Ubuntu 20.04. I’ll wait until noon tomorrow before loading up Ubuntu 18.04 in case you are able to come up with anything from the log files.

Hmmm… why are you dumping these commands on the thinkpad…

What I expected is all these from jetson nano…

I mean even the Xorg.0.log is from jetson nano too…

Actually, no info is needed from your host machine…

I accidentally was looking on my host computer for the Xlog file.

You were right, I did not send you the whole file output. Here it is:
Well spotted. Yes, I just noticed realized that I made this mistake a few minutes ago and am just going to sent you the output from the Jetson Nano.

  1. Please share full xorg log. You can attach it as s file on this forum.

  2. If you use command “xinit &” on your nano, will you see something on the monitor?

If not, could you share the xorg log again? There should be some error telling what happened.

Please just use ethernet or wifi to send out the file to your host and upload the full log…

Your comment again shows that it seems another partial log from editor…

Also, why are you saying that you have no graphical environment but you shared a log with no monitor connected?
What kind of graphical environment do you want to see when no monitor is connected?

Ok, I’ll see what I can do. Thanks.

As a beginner, I’m having a little trouble with the permissions with using scp. I will get it sorted out though.

I’m expecting to see the graphical environment shown at about 11 minutes into the following YouTube video from Nvidia:

I believe that I should be seeing this even in Headless mode. I did try connecting a HDMI monitor and USB mouse and keyboard but the monitor says that there is no input.
