phantom DM in 15.10

I have a 15.10 installation on intel 945G in which ps -A reports sddm
running, but there is no GUI screen to be found on any vtty. Startx works,
creating a session on :1 (on whichever vtty logged into), since the phantom
DM is laying claim to :0 on vtty7. sddm.log shows sddm-helper exited and
greeter stopped, which is a poor clue to where the problem lies. Systemctl
confirms sddm running:
● sddm.service - Simple Desktop Display Manager

Feb 21 22:50:54 gx620 sddm-helper[810]: pam_unix(sddm-greeter:session):
session opened for user sddm by (uid=0)
Googling seems to indicate this problem has to do with PAM, but nothing I've
found so far has described a solution that works here. /var/log/sddm.log also
points to PAM:
(II) DAEMON: Initializing...
(II) DAEMON: Starting...
(II) DAEMON: Adding new display 0 on vt 7 ...

(II) DAEMON: Greeter session started successfully
(II) HELPER: [PAM] Ended.
(WW) DAEMON: Auth: sddm-helper exited with 2
(II) DAEMON: Greeter stopped.
Any ideas how to fix this?
