Hello,

Is there a script to run / command to run for bringing up the display manager on boot up? For some reason our ORIN is always in the state of display manager being stopped and will only come up after running sudo systemctl start gdm. Previously, Ubuntu desktop login screen would automatically show when Orin is switched on.

Dear @chris.hoffman ,
Could you share the output of sudo systemctl status gdm after booting. Also, what is the output of ls -la /etc/init.d/?

@SivaRamaKrishnaNV
I switched off the Orin and switched it back on to check the status:

root@tegra-ubuntu:~# sudo systemctl status gdm

@SivaRamaKrishnaNV any feedback on this?

6

Dear @chris.hoffman,
Could you check reinstalling gdm fixes the issue?

7

@SivaRamaKrishnaNV are you able to share the steps specific to the Orin for that? I’ve tried other ways before, but they did not help.

8

May I know what you have tried and not worked?

@SivaRamaKrishnaNV

  1. To install the minimal GNOME desktop environment, use your system’s package manager to install the GUI and gdm3 window manager.

$ sudo apt install gnome-session gdm3

  1. After installation is complete, reboot your system and you will be presented with a GNOME login.

$ reboot

Dear @chris.hoffman
Hi , Maybe this can be fixed
Directory：/etc/system/system/
Symbolic Link File：display-manager.service
Link Destination：/lib/systemd/system/gdm3.service

①$ cd /etc/system/system/
②$ ln –s /lib/systemd/system/gdm3.service display-manager.service
③reboot

11

Hi @chris.hoffman,
Note that, reboot command does not work on Orin. Please see CLI reboot and poweroff commands do not work .
common_if_testapp -mcureset needs to be run on tegra to reboot.
