Lutris

Lutris

Do not

linuwux lutris
linuwux lutris lutris:rungameid/N

That wraps the Lutris UI, not the game (Common mistakes).

Do

1. Install LinUwUx (Install).
2. Right-click the game → Configure.
3. Use GE-Proton / CachyOS via your Proton runner setup (not “system Wine only” if you rely on Proton builds).

Option A — Command prefix (recommended)

System options → Command prefix:

~/.local/bin/linuwux

Option B — Environment variable

System options → Environment variables:

Key	Value
LD_PRELOAD	/home/YOU/.local/lib/liblinuwux.so

Use your real home path. If something else already sets LD_PRELOAD, prefer Option A so the wrapper can append.

4. Save. Start the game from Lutris as usual (no linuwux lutris in a terminal).

Verify

Enable LINUWUX_DEBUG=1 on that game’s environment and confirm the library loads on the game/Proton side, not only on Lutris Python helpers. See Troubleshooting.
