I launch weston, with the fbdev backend: backend=/usr/lib/libweston-9/fbdev-backend.so then set my environment: $ export WAYLAND_DISPLAY=wayland-0 $ export XDG_RUNTIME_DIR=/run/weston $ export XDG_SESSION_TYPE=wayland $ export GDK_BACKEND=wayland then try to launch MiniBrowser and get nothing useful on the graphics screen and this error on the cli: $ /usr/lib/wpe-webkit-1.0/MiniBrowser ** (MiniBrowser:127436): WARNING **: 09:09:33.548: WindowViewBackend: cannot yet handle wpe_fdo_shm_exported_buffer. I can launch luakit in weston with this setup, but not MiniBrowser. I have not tried this on an HDMI connected display (/fb0). This is on an RPi 3B+ running Arch Linux kernel 5.10.25 aarch64.
