FAQ

Why can't I use my already installed Wine runners from Steam?

Lumoria is designed to work in a fully sandboxed environment. While it is possible to interact with the Steam compatibility tools in the Sandbox by granting extra permissions, it is not worth the headaches to save ~1.2gb worth of storage. We've found in a lot of cases that people have wound up with corrupted Wine Runners. Lutris or Heroic Launcher are good alternatives if you want to maintain one set of Wine Runners.

Where are files located?

Lumoria uses the XDG Base Directory Specification. This means:

In Flatpak / Sandbox:

• ~/.var/app/net.windower.Lumoria/cache
• ~/.var/app/net.windower.Lumoria/config
• ~/.var/app/net.windower.Lumoria/data - This is where game data will default to install.

Outside of Sandbox:

• ~/.cache/lumoria
• ~/.config/lumoria
• ~/.local/share/lumoria
• ~/Games/Lumoria - This is where game data will default to install

My file paths look weird while running the Flatpak

This is normal. The Flatpak maps all paths to the sandboxed environment which will end up under /run/user/<user_id>/doc/<somehash>. We only have full access to ~/.var/app/net.windower.Lumoria and when you use Browse you are granting permission to Lumoria to use that directory via XDG Desktop Portals.

gamescope-session - Nothing Launches

If you are using Wine Wayland mode while running inside of Gamescope (Gaming Mode) and the game refuses to start, it might be caused due to Steam's overlay not being fully compatible with Wayland. To resolve go to Manage Prefix > Advanced and add an environment variable with a name of LD_PRELOAD and no value.
