  Devices needing ACLs are marked by "uaccess" TAG in udev rules. For
/dev/dri/*, the rule is in /usr/lib/udev/rules.d/70-uaccess.rules:

SUBSYSTEM=="drm", KERNEL=="card*", TAG+="uaccess"

You should verify this with "udevadm info --name=/dev/dri/card0 --query=property".

  Yet, the way you start graphical desktop is suspicious at least. I'm not
entirely sure if logind registers new graphical session and if ACL
are set.
  This, in turn, you can verify by "loginctl" with various commands - list-sessions,
session-status etc.
