You can find other (older, smaller, checksum, RCs) release related packages and files on the [releases page](https://github.com/f3d-app/f3d/releases).
You can find other (headless, older, smaller, checksum, RCs) release related packages and files on the [releases page](https://github.com/f3d-app/f3d/releases).
You can also find there the [nightly release](https://github.com/f3d-app/f3d/releases/tag/nightly) to test the development version of F3D.
See the [desktop integration](DESKTOP_INTEGRATION.md) section in order actually integrate the binary release in your desktop.
Alternatively, you can build F3D yourself by following the [build](../dev/BUILD.md) guide.

A work around to this issue is to use a virtual Xorg server like Xephyr or Xvfb in all the `f3d-plugin-xxx.thumbnailer` files.
Here is how your `Exec` line should look to use `xvfb-run`. Keep in mind running xvfb can be very slow.

`Exec=xvfb-run f3d --dry-run -sta --no-background --output=%o --resolution=%s,%s %i`

Another workaround is to build VTK with EGL or osmesa support and then build F3D yourself against
this custom VTK build.
In that case, you want to use the headless version of F3D that rely on EGL instead of Xorg, available in the [releases page](https://github.com/f3d-app/f3d/releases).
If you use the portable archive, make sure to extract it somewhere the sandboxing system has access to, eg: `/usr/opt/`.
