We have a orin develop kit today,and i flash the kit by sdkmanager,show success!
but when power the kit ,no image no display monitor;
here is the uart log;
show last line is:
Please wait for auto system configuration setup to complete…
orin-uart-log.txt (83.5 KB)
Please run ./tools/l4t_create_default_user.sh before flashing and flash it again.
After you can operate the console, please rmmod nvidia.ko, set dmesg log level higher.
dmesg -n 7
And then insmod the nvidia.ko module again with below command.
sudo insmod /lib/modules/$(uname -r)/extra/nvidia.ko NVreg_RmMsg=":"
After run ./tools/l4t_create_default_user.sh and flash.
can operate the console,i try to romod nvida.ko,but in use.
and the monitor still shows nothing.
The monitor will not work. What we are doing is just dumping log. I didn’t provide any magic trick to make your monitor work.
Please kill gdm3 service so that nvidia_modeset.ko could be rmmod.
I’m running into the same issue. I’ve attached my output from running the following:
sudo service gdm3 stop sudo rmmod nvidia_modeset.ko sudo rmmod nvidia.ko sudo dmesg -n 7 sudo insmod /lib/modules/$(uname -r)/extra/opensrc-disp/nvidia.ko NVreg_RmMsg=":" dmesg > dmesg.txt
Note how my insmod command is slightly different. The only thing in the extra directory hwas the opensrc-disp directory.

Could you also hotplug the monitor cable under such state and dump dmesg again? Will you see any new log under such case?
I rebooted the Orin with the monitor unplugged, ran those commands, plugged in the monitor, then unplugged the monitor all while keeping an eye on dmesg.
I’ve attached the output:
dmesg-monitor-in-out.txt (76.6 KB)
After I ran all those commands, but before I plugged in the monitor, the last line was at 104.784132.
Plugging in the monitor caused the line at 116.231236.
Unplugging the monitor caused the line at 169.257698.
(My apologies for using a different username, I’m having trouble logging into my other account)
Could you also enable gdm service and check the dmesg after current status?
With the monitor still unplugged, I restarted gdm3 and got this output from dmesg:
after-gdm3.txt (134.3 KB)
Then I plugged in the monitor:
after-gdm3-then-monitor-in.txt (134.1 KB)
Is your monitor a pure DP monitor? or you are using some adapters here?
I’m using a DP-to-HDMI adapter (It works with other devices).
Is that adapter an passive one or active one?
Do you also load nvidia-modeset.ko back or not? If not, please load it too.
And after load it back, restart gdm and share the monitor info.
I think you need the DP-DP cable.
I used DP-HDMI first and find the monitor no display then after changed DP-DP cable the monitor is ok!
For the adapter, I’m assuming it’s active as it has a small box component.
I didn’t load nvidia-modeset.ko back, so I rebooted and ran the following commands:
sudo service gdm3 stop sudo rmmod nvidia_modeset.ko sudo rmmod nvidia.ko sudo dmesg -n 7 dmesg > dmesg1.txt sudo insmod /lib/modules/$(uname -r)/extra/opensrc-disp/nvidia.ko NVreg_RmMsg=":" dmesg > dmesg2.txt sudo insmod /lib/modules/$(uname -r)/extra/opensrc-disp/nvidia-modeset.ko NVreg_RmMsg=":" dmesg > dmesg3.txt sudo service gdm3 start dmesg > dmesg4.txt # Note: plugged in monitor dmesg > dmesg5.txt export DISPLAY=:0 xrandr
The output of xrandr was:
No protocol specified Can't open display :0
Are you sure gdm3 is on? Could you check /var/log/Xorg.0.log and see if it has any error indicating gdm3 fails to launch?
No issues, as far as I can tell.

Looks like not able to detect. Please change the adapter or directly use native DP.
