Description Alexander Larsson 2019-12-19 13:57:47 UTC

I noticed that the fedora flatpak didn't pick up the nvidia driver extension.

I added this to the platform metadata (/var/lib/flatpak/runtime/org.fedoraproject.Platform/x86_64/f31/active/metadata):

[Extension org.freedesktop.Platform.GL]
version = 1.4
directory = lib/GL
subdirectories = true
no-autodownload = true
autodelete = false
add-ld-path = lib
merge-dirs = vulkan/icd.d;glvnd/egl_vendor.d;OpenCL/vendors
download-if = active-gl-driver
enable-if = active-gl-driver

And then created the /usr/lib/GL directory in the runtime:

  mkdir /var/lib/flatpak/runtime/org.fedoraproject.Platform/x86_64/f31/active/files/GL

And then i could run:

 flatpak run  org.mozilla.Firefox about:support

and it reported the webgl stuff as working with the nvidia driver.

Any reason we're not doing this by default?

Additionally we need to configure libglvnd to find the json files in the extension.
With the above example they will appear as:
  /usr/lib/GL/glvnd/egl_vendor.d/10_nvidia.json

It seems like the default libglvnd looks in /usr/share/glvnd/egl_vendor.d and /etc/glvnd/egl_vendor.d, and fedora choses the one in /usr for packaging its drivers, leaving the other for sysadmin overrides. Since there is no sysadmin overrides in flatpak we can use this by making the /etc/glvnd a symlink to /usr/lib/GL/glvnd which will then be filled in by the extension.

Comment 2 Alexander Larsson 2019-12-19 14:48:46 UTC

You also need something similar for vulkan and opencl:

[📦 org.mozilla.Firefox ~]$ ls /usr/lib/GL/OpenCL/vendors/ /usr/lib/GL/vulkan/icd.d/
/usr/lib/GL/OpenCL/vendors/:
nvidia.icd

/usr/lib/GL/vulkan/icd.d/:
nvidia_icd.json
