Java vs bedrock edition
Hi there! First of all: This forum is mostly about Flathub as a platform. If you want advice or help specific to an application, you can find links to app-specific help resources on its app page. I will try to give some pointers here, but if you need more in-depth advice, I recommend using the help resources of the application in question. jkgoose: > […], I’m noticing this program only downloads the java edition from the google app store vs the microsoft bedrock edition. […] By “this program”, I assume you’re referring to the Minecraft Bedrock Launcher? First of all, this is not using a “java edition from the google app store”, since this doesn’t exist. The Java edition is separate, bought on Minecrafts website, and only available on desktop platform (though including Linux natively). The Minecraft you find on the Google Play Store is the Bedrock edition, same as the one found on iOS or in the Microsoft Store. Now, the “Minecraft Bedrock Launcher” is just a small wrapper to make the Android version of Minecraft Bedrock run on Linux. Using the Microsoft Store version would require a wrapper for a Windows version. So its not possible with the current launcher to use a version of Minecraft Bedrock bought on the Microsoft Store. I’d assume you could login with your Microsoft Account in the game itself though, and transferring worlds should be possible by manually copying them.

How to increase the file descriptor limit (NOFILE/ulimit -n) for a Flatpak app? VKD3D shader cache issue
**Hello,** I’m facing a problem with the **Heroic Games Launcher (com.heroicgameslauncher.hgl)** and a game (**Horizon Forbidden West**) running via Wine/Proton. The game uses VKD3D-Proton to cache DX12 shaders. **The Problem:** Every time I exit the game, the shader cache merge process (from `vkd3d-proton.cache.write` to `vkd3d-proton.cache`) seems to fail. I suspect this is because the file descriptor limit (`ulimit -n`) inside the Flatpak sandbox is only **1024**. The process likely needs to open thousands of files to merge the cache and hits this limit. * Proof: `flatpak run --command=sh com.heroicgameslauncher.hgl -c "ulimit -n"` returns **1024**. * Result: The `.write` file is left behind, the main `.cache` doesn’t update, and the game recompiles all shaders from scratch on every launch (taking several minutes). **My Question:** Is there an official or recommended way to **increase this`RLIMIT_NOFILE` for a specific Flatpak application**? **What I’ve tried (unsuccessfully):** 1. Creating a systemd user override for the app’s scope (e.g., `app-flatpak-com.heroicgameslauncher.hgl-*.scope`). This didn’t work because the limit seems to be enforced earlier by the sandbox (`bwrap`). 2. Setting the `WINE_FD_LIMIT=1048576` environment variable inside the sandbox. This does not affect the actual OS-level limit. **Is this the right approach?** Would a `flatpak override` command like the one below work? If so, is there a specific parameter that directly controls the file descriptor limit for the sandboxed process? flatpak override --user com.heroicgameslauncher.hgl --env=WINE_FD_LIMIT=1048576 # (plus other necessary permissions) Or is there another mechanism I should use? If possible, could you provide an example of a working configuration? **System Information:** * Distribution: Fedora Linux 42 (Rawhide) * Flatpak version: `flatpak --version` → **1.16.2** * Affected application: `com.heroicgameslauncher.hgl` Any guidance would be greatly appreciated. This issue severely impacts the usability of demanding DX12 games through Flatpak. Thank you for your help!
