I am not having trouble starting xdm via /etc/ttys; my environment is
known to differ from yours in the following ways:
* My ports (save for x11/nvidia-driver and misc/compat8x) are built
under stable/8. (I track stable/8, stable/9, and head on a daily
basis, and have a common /usr/local among them. I also update
any installed ports that have updates available daily.)
* I am running FreeBSD/i386, vs. FreeBSD/amd64.
* My last 2 updates were r233994 (yesterday) and r234031 (today).
* I have a mildly hacked-up startup script for xdm. I doubt this is an
issue -- I've been doing this since 2006/03/05 19:04:03 (according to
the RCS log), though I have modified the script a few times
since its inception. But the point here is that I'm not directly
invoking the xdm executable from /etc/ttys.
* I don't know that this is different, but it may well be: my xorg.conf
includes a stanza:
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
because my experiences with hald & dbus were so unpleasant. I don't
use them; I don't even try to start them.
Peace,
david
