Jetson TX2 cannot be opened

[murase.koki.q2]

Jetson TX2 suddenly stopped. It cannot move to ubuntu screen. I can only see the following screen flashing and cannot open ubuntu. How can I fix it?

Press ctrl + alt + F1 ~F6 and see if you can switch to console mode.

If your can, after you enter console mode, run dmesg > log.txt and attach that log here.

Thank you.
When I press ctrl + alt + f2, I can enter console mode.
I log in and connect LAN to CPU, Ubuntu are launched normally.

But I can’t understand why this situation occures including the screen flashing. If you know that, please tell me why.

[WayneWWW]

There is no answer from me. As I said in previous comment, you need to share me the log when desktop fails to launch. Otherwise I won’t know.

[murase.koki.q2]

When I entered the console mode and logged in, it stated that it was not connected to the net, so I connected it to the LAN, and it was back up before I could command dmesgs.
Sorry, Thank you for your response.

The Xorg log should contain useful information even if something else goes wrong. To find the most recent log:
ls /var/log/Xorg.*.log | tail -n 1
…then post the log. Probably it will be Xorg.0.log.
