Hi,
I flashed Jetson Xavier AGX with JetPack 5.1 (rev.1) using sdkmanager (1.9.2.10888) using a Ubuntu2004 host.
Strangely, when the Xavier boots up with HDMI cable plugged in, I see the Nvidia logo flash on the screen with a few scrolling lines of boot up but the display screen then goes blank. I am able to ssh into the machine but not able to VNC into it.
However if I power-up the xavier without the HDMI, allow it to boot-up fully and then plug in the HDMI cable, I see ubuntu2004 home screen on display and able to log in. VNC still doesn’t work.
Yes, the dmesg says no NVIDIA GPU and later tegrastats lists the GPU. I am not clear if something went wrong between flashing and installing via sdkmanager.
I didn’t configure but the xavier was used by another teammate.
My bad: here is the xrandr output when the HDMI is connected:
Screen 0: minimum 8 x 8, current 1600 x 900, maximum 32767 x 32767
HDMI-0 connected primary 1600x900+0+0 (normal left inverted right x axis y axis) 440mm x 250mm

Didn’t you say it was just flashed with sdkamanger by you? Why does other teammate’s work matter?
Could you use some xrandr command like below and check if GUI can show up or not?
xrandr --output HDMI --mode 1920x1080
Also, could you ask your teammate was this board ever showing any GUI on his side in the past? If it was, which jetpack was flashed on it at that time?
As I said in the first post, we don’t guarantee any behavior of custom board with default jetpack.
My observation has 2 scenarios:
Scenario1:
Strangely, when the Xavier boots up with HDMI cable plugged in, I see the Nvidia logo flash on the screen with a few scrolling lines of boot up but the display screen then goes blank. I am able to ssh into the machine but not able to VNC into it.
Scenario2:
However if I power-up the xavier without the HDMI, allow it to boot-up fully and then plug in the HDMI cable, I see ubuntu2004 home screen on display and able to log in. VNC still doesn’t work.
My objective is to be able to use the xavier both directly with HDMI plugged in and also remotely with VNC.
