      Hi,

      Weston 1.9.0, built from the master branch of AGL, fails to start on Porter board if there is no input device attached (keyboard or mouse):

      [[0;1;31m●[[0m weston.service - Weston reference Wayland compositor

      If I attach a keyboard Weston systemd service starts successfully but I have just a blank screen.

      Weston version is 1.9.0. According to weston.ini desktop shell and DRM backend is being used.

      The issue might be related to SPEC-223 as well as to an old issue in Weston which has been fixed in Dec 2014:

      I have some experience from another project regarding the failing Weston if there are no input devices. There is very good article about that by Derek Foreman in Samsung OSG blog: https://blogs.s-osg.org/when-is-a-keyboard-not-a-keyboard/

      Best regards, Leon
