[ Impact ]
* On NVIDIA Jetson Orin platforms installed with candidate Ubuntu for
Jetson images (https://cdimage.ubuntu.com/nvidia-tegra/ubuntu-
server/jammy/daily-preinstalled/), a monitor connected to the
DisplayPort will not light up again after a suspend-resume cycle
* In the same configuration, a monitor will not display any output if
it is connected after the system boots or when being disconnected and
reconnected while the system is running
* These issues affect Ubuntu 22.04 certification on Jetson Orin
platforms.
- * This will be fixed by adding the file /etc/modules-load.d/nvidia-
+ * This will be fixed by adding the file /etc/modules-load.d/nvidia-
drm.conf that force-loads the nvidia-drm module.
* The module will also need to be loaded with the appropriate
parameters modeset=1 and fbdev=1 which will be the default starting with
the tegra-igx kernel 1019
[ Test Plan ]
* Install the candidate Ubuntu for Jetson image
(https://cdimage.ubuntu.com/nvidia-tegra/ubuntu-server/jammy/daily-preinstalled/manual/
– build 20240919) on a Jetson AGX Orin
- * Upgrade to latest packages, making particularly sure to install the latest
jetson meta-package (apt install linux-nvidia-tegra-igx-jetson) and kernel
package (1019 ABI or later) from jammy-updates
- * Reboot the system without a monitor connected, connect a monitor, see that
it doesn't show any video output
- * Reboot the system with a monitor connected, see that it shows console
output, trigger a suspend-resume cycle with the command below and see that
video output is not coming back (you can connect over e.g. serial or SSH to
confirm the system is truly back from suspend):

- * Install nvidia-tegra-defaults from -proposed; NB: there are no noble
- images, but it's fine to install the noble-proposed build on top of the
- jammy image to confirm it will work properly after an upgrade

+ nor oracular images, but it's fine to install the noble-
+ proposed/oracular-proposed build on top of the jammy image to confirm it

- * Rerun the above monitor testing instructions rebooting between tests
+ * Rerun the above monitor testing instructions rebooting between tests
and confirm that console output works even when the monitor is plugged
after boot, or after a suspend-resume cycle
[ Where problems could occur ]
* No additional problems should happen as the nvidia-drm kernel module
is usually automatically loaded with these parameters when it is pulled
in by an X11 dependency. Nvidia releases 2 desktop images using that
mechanism (Jetpack and BaseOS). This intends to fix the behavior on a
Ubuntu server image.
* If a user installs this package on a different platform, running a
different kernel, the nvidia-drm kernel module will not be present and
subsequently not loaded and therefore does not impact such systems.
[ Other Info ]
* This is related to two private bugs being discussed between Canonical
and NVIDIA; because NVIDIA uses the kernel packages in their own Ubuntu-
based images, it's not possible to include this fix in the kernel
package itself as NVIDIA doesn't want nvidia-drm to be force loaded for
their usage
