Hi, I am unable to get the ubuntu desktop to show up after installing it following the instructions here: I have had exactly the same issues as this topic here: Error trying to connect monitor. I see the exact NV_DISPLAY_HUB error, the switch error, and also the same pam.d queries. I am also using a Dell 1080p monitor. I have gotten the display to work, but there is just no ubuntu, despite installing it. I actually followed the steps from this topic: flash 5.2.6, then try to install the ubuntu desktop on Xavier A (no display), then again on Xavier B (display shows), refresh Xavier A (display now shows), but none have given me the ubuntu desktop. I have also done step 4 every time with the automatic login. I’d be happy to attach logs for a certain flashing if needed. Any suggestions?

Dear @atseng,
Could you attach logs here?

What do you see in the display. Could you attach a picture.

I just see black but the screen is on as the LED backlight is on. For the logs, which steps should I redo?

Dear @atseng,
Please attach ~/.nvsdkm folder. Also, could you check increasing brightness of monitor.

What I did was to flash each tegra independently, then follow the instructions in the guide, in step 4 instead of adding those lines, I uncommented the lines that were already in the .conf file (with the same commands), i just changed the AutomaticLogin for nvidia and reboot.

I have the exactly same issue here. Is there any update on this topic? In the forum it seems that many people experience this issue.
