Hello
After following the steps below, gui won’t boot.
How do I go back?
nveglglessink (Windowed video playback, NVIDIA EGL/GLES videosink using Wayland backend)
You can also use nveglglsink with the Wayland backend, instead of the default X11 backend.
Ubuntu 16.04 does not support the Wayland display server. That is, there is no UI support to switch to Wayland from Xorg. You must start the Wayland server (Weston) using the target’s shell before performing any Weston based operation.
To start Weston:
The following steps are required before you first run the GStreamer pipeline with the Wayland back end. They are not required on subsequent runs.
1.Stop the display manager:
$ sudo systemctl stop gdm
$ sudo loginctl terminate-seat seat0
2.For Weston 6.0 use the tegra_drm driver:
$ sudo ln -sf /usr/lib/aarch64-linux-gnu/tegra/libnvgbm.so /usr/lib/aarch64-linux-gnu/libgbm.so.1
$ sudo modprobe tegra-udrm modeset=1
3.Unset the DISPLAY environment variable:
$ unset DISPLAY
4.Create a temporary xdg directory:
$ mkdir /tmp/xdg
$ chmod 700 /tmp/xdg
5.Start the Weston compositor:
$ sudo XDG_RUNTIME_DIR=/tmp/xdg weston --idle-time=0 &
To run the GStreamer pipeline with the Wayland backend:
Use the following command to start the GStreamer pipeline using nveglglesink with the Wayland backend:
sudo XDG_RUNTIME_DIR=/tmp/xdg gst-launch-1.0 filesrc
location=<filename.mp4> ! qtdemux name=demux ! h264parse !
omxh264dec ! nveglglessink winsys=wayland
