Can't get a login prompt after stop GUI

Hi,

We want to use the sample 08_video_dec_drm to do a  DRM rendering demonstrate.

By steps on https://docs.nvidia.com/jetson/l4t-multimedia/l4t_mm_08_video_decode_drm.html.

  • Ensure the Ubuntu desktop is disabled:

  •  $ sudo systemctl stop gdm

  •  $ sudo loginctl terminate-seat seat0

  • Install nvidia-drm driver for Jetson Orin:

  •  $ sudo modprobe nvidia-drm modeset=1

    We can not get a login prompt on the screen after typing the command “sudo systemctl stop gdm” and “sudo loginctl terminate-seat seat0”… Even pressing pressing Ctrl+Alt+Fx. Just get a black screen, no signal.

    We have tried those command on Jetson Xavier before, we can pressing Crtl+Alt+Fx to get a login prompt.

    And we make sure the device is working, we can run the 08_video_dec_drm through SSH.

    But we need a method to do demostrate on Jetson NX directly, not by another computer.
    And we want to stop and start GUI by stop and start gdm as Jetson Xavier.

    Device: Jetson NX 8G
    Kernel: 5.10.104-tegra.
    L4T: # R35 (release), REVISION: 3.1, GCID: 32827747, BOARD: t186ref, EABI: aarch64, DATE: Sun Mar 19 15:19:21 UTC 2023

BR,

Hi,
This is expected since framebuffer console is not supported on Jetpack 5 releases. We are evaluating to support it in the future.
