The following are install instructions for custom Jetson BSP flatpaks made by myself to alllow for hardware accelerated GPU use (OpenGL, GLES, EGL, and Vulkan) in all flatpaks. Flatpak’s for BSP 32.3.1, 32.7.3, 35.1.0, and 35.2.1 have been made. It is simple to make your own following the sources if you need to make one for any other BSP version. 32.3.1 and 32.7.3 have been tested fully functional, however I do not own Jetson hardware capable of running 35.x.x so you can comment if the flatpak’s work or not :)

Install script. Make sure are within your sudo timeout before copy/pasting directly into your terminal:

# For Ubuntu Bionic, you NEED the flatpak PPA first since the flatpak version from ubuntu no longer functions with flathub
sudo apt update
# install packages for add-apt-repository and glxinfo programs
sudo apt install software-properties-common mesa-utils -y
sudo add-apt-repository ppa:alexlarsson/flatpak -y
sudo apt update

# install flatpak
sudo apt install flatpak -y

# add flathub as a repo
sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

# the folllowing function should be run with display access for glxinfo to determine the current system BSP version
BSP_version="$(glxinfo -B | grep -E "NVIDIA [0-9]+.[0-9]+.[0-9]+$" | head -n1 | awk '{print $(NF)}')"

Sources (json files for creating the flatpaks) can be found in their respective subfolders:
https://github.com/cobalt2727/L4T-Megascript/tree/master/assets/Flatpak
Packaging can be accomplished following these commands in the same folder as the json file.
Change the json filename and output version name as required:

sudo flatpak-builder -v --force-clean --delete-build-dirs --disable-cache --arch=aarch64 --repo=nvidia builddir org.freedesktop.Platform.GL.nvidia-tegra-32-3-1.json
sudo flatpak build-bundle ./nvidia org.freedesktop.Platform.GL.nvidia-tegra-32-3-1.flatpak runtime/org.freedesktop.Platform.GL.nvidia-tegra-32-3-1/aarch64/1.4

you should also pin the runtime (so flatpak autoremove won’t remove it)

run this command after the others in the same terminal

sudo flatpak pin --system runtime/org.freedesktop.Platform.GL.nvidia-tegra-${BSP_version//./-}/aarch64/1.4

user installed flatpaks (as oppsed to system installed) will also need the overrides

flatpak override --user --device=all
flatpak override --user --share=network
flatpak override --user --filesystem=/sys
