Hi Leon, I'm not sure we want to enable pam for everyone using systemd, there may be many systemd users who don't use weston. If we do want to enable pam whenever systemd is in use, the better place to do it is in meta/conf/distro/include/init-manager-systemd.inc. An alternative, though not the most satisfying, may be to add a REQUIRED_DISTRO_FEATURES check to the l4t-graphics-demos recipe in meta-tegra. Best regards, -- Paul Barker
