I just found out that the NetBSD default error file for xdm is
in /var/log.  This contains:

AUDIT: Fri Oct 22 10:36:28 1999: 180 X: client 3 rejected from local host
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
Error: Can't open display: :0
AUDIT: Fri Oct 22 10:36:45 1999: 180 X: client 3 rejected from local host
Xlib: connection to ":0.0" refused by server
Xlib: Client is not authorized to connect to Server
Error: Can't open display: :0

Thanks in advance. Cheers,
