ubiquity-dm opens up a PAM session and specifically sets logind variables to open a "greeter session" (seat0). please check with loginctl that a correct logind session is opened for ubiquity-dm. if there is logind session opened, further debugging will be required to figure why /dev/dri is not available / not tagged for seat0.
