weston-launcher starts desktop-shell which dies, why it die?

[tematibr]

Hi, trying to run wayland weston with drm, but no success.

Looking in logs the weston-launch has "launching /usr/libexec/weston-desktop-shell" so that looks ok, and the PID file in XDG_RUNTIME_DIR is created, but then it looks like the weston-desktop-shell dies with error: "failed to create display, connection reset by peer".

The WAYLAND_DISPLAY environment variable which should have been set by weston is also not set.

Most strange is that the wayland-0 and wayland-0.lock files in XDG_RUNTIME_DIR are created ( for some reason they are not deleted after weston-desktop-shell dies).

Any ideas?
