Nvidia jetson xavier nx Gui login issue

Currently we are facing a problem while login in GUI ,we are getting infinite login loop.Kindly help !

hello kumarbulkesh1999,

may I know which JetPack release you’re working with, and, what’s the modification you’d done.
please also setup serial console to gather uart logs for reference,

we are using JetPack release 32.4.3 , boot_dmesg_main.txt (99.2 KB)

hello kumarbulkesh1999,

according to those kernel messages, it looks kernel side did not hanging.
there’re several paragraph report display related errors,
for example,

[ 1460.398417] snd_hda_codec_hdmi hdaudioC0D3: HDMI: Unknown ELD version 0
[ 1460.718352] snd_hda_codec_hdmi hdaudioC0D3: HDMI: Unknown ELD version 0
[ 1461.038373] snd_hda_codec_hdmi hdaudioC0D3: HDMI: Unknown ELD version 0

may I know what’s the display monitor you’re used.

Hi JerryChang
We are using HP Compaq LA2206x
(We are able to see the GUI by entering “startx” command in ther terminal)

hello kumarbulkesh1999,

why you need startx to enable X window, were you running in headless mode?

Hello JerryChang
I searched on the google and i saw in one of the link to hit startx command to enter in GUI mode

hello kumarbulkesh1999,

were you installing JetPack release via NVIDIA SDK Manager?
it’s by default having GUI and you don’t need additional commands to enable X window.

Hi JerryChang
We are able to see the login page but after entering the password it again ask for password so it’s become an infinite login loop

hello kumarbulkesh1999,

is there password mismatch failures?
are you able to repeat the steps to flash the board again for verification, thanks

Hii JerryChang
No, There is no password mismatch
we have done the steps multiple times after flashing the board

hello kumarbulkesh1999,

could you please also take a video clip about the issue,

Hii JerryChang
I am not able to upload the video due to size issue
when Gui login appears we enter password .Then it will ask for password infinite time

how about upload the video to the youtube channel and mark the content as private, i.e. only viewable via the shared link.

hello JerryChang
here I am attaching the Video Please look into this matterVID-20201130-WA0003.mp4.tar.gz (3.1 MB)

Hi kumarbulkesh1999,

Are you replace kernel modules?
Please show us the size of nvgpu.ko. Thanks!

Hi Carolyuu
Here I am attaching the size of nvgpu.ko file in a text file
size_ko.txt (622 Bytes)

It is a known issue that nvgpu.ko must be stripped to prevent the GUI login problem.

Please run the command for your nvgpu.ko.

$ <tool_chain_path>/aarch64-linux-gnu-strip -–strip-unneeded <path-of-kernel-module.ko>


Hii WayneWWW
We just tried your given solution,but still we are facing the same
Could you please tell another solution

So did you see the nvgpu.ko size gets decreased on your device?
