Launching

Launching

LinUwUx must load into the Wine/Proton game process, not into Steam/Lutris/Heroic as a whole.

Pattern

1. Install (Install).
2. Set runner to GE-Proton or CachyOS Proton.
3. Put linuwux on the game launch path only.

By launcher

• Steam — simplest; best tested
• Lutris — command prefix or env on the game entry
• Heroic
• Faugus / umu

Wrapper vs raw LD_PRELOAD

Method	Notes
linuwux %command%	Preferred; appends to existing LD_PRELOAD (needs ~/.local/bin on PATH)
LD_PRELOAD=…/liblinuwux.so	Easy to clobber overlay/other preloads if you replace instead of append

Debug

LINUWUX_DEBUG=1 linuwux %command%
