Public bug reported:
[ Impact ]
* On nvidia tegra platforms, a connected monitor will not light up
again when put into a suspended state and subsequently woken up by an
rtcwake command or when being hot-plugged.
* This will be fixed by including a file in /etc/modules-load.d/nvidia-
drm.conf that 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 ]
* The user needs to connect a monitor to the display port of one of the
affected devices and observe that the console appears on the screen.
Then run the following command:
$ sudo rtcwake -m no -s 30 && sudo systemctl suspend
[ Where problems could occur ]
* No additional problems should happen as this package This kernel
module is loaded with these parameters already by official nvidia Linux
releases indirectly when it is pulled in by an X11 dependency. If the
module is not present, it will also not be loaded.
[ Other Info ]
* This is related to both launchpad bugs #2071409
