QT_QPA_PLATFORM=offscreen alone is NOT sufficient on Redox —
Qt6 still loads libqwayland.so despite the env var. The wrapper
now renames libqwayland.so to .disabled before launching kded6,
forcing Qt to fall back to the offscreen plugin which works.
This is the most reliable fix: physically preventing Qt from
finding the wayland plugin.
kded6 wrapper (/usr/bin/kded6 → kded6-wrapper.sh → kded6.real):
- Sets QT_QPA_PLATFORM=offscreen before executing real kded6
- Works regardless of launch mechanism (init, D-Bus, direct)
- No dependency on #ifdef Q_OS_REDOX, D-Bus Environment=, or build cache
- kded6 is a headless D-Bus daemon — Wayland adds no functionality
redox.patch: added null guards to wayland-client.c (wl_proxy_add_listener,
wl_proxy_get_version, wl_proxy_get_display) — durable patch for when
libwayland build is fixed.
