kdm/startkde problem after upgrade

[Andriy Babiy]

Hi everyone!

$ uname -a
FreeBSD ABC.DEF.com 6.2-STABLE FreeBSD 6.2-STABLE #0: Wed Jul 11 06:07:39 
PDT 2007     root@:/usr/obj/usr/src/sys/AMD64  amd64

kdm is configured as a login manager in /etc/ttys.

After upgrade to KDE 3.5.7 and X server 7.2 (that was time consuming, but 
no errors) I receive an error message on startup:
Jul 16 00:13:10 FreeBSD-amd64 kdm-bin[792]: X server "/usr/X11R6/bin/X" 
cannot be executed
Jul 16 00:13:10 FreeBSD-amd64 kdm-bin[789]: X server for display :0 can't 
be started, session disabled

When I logged in, startkde brings another error message:
xsetroot:  unable to open display ''
Warning: kbuildsycoca is unable to register with DCOP.
kbuildsycoca running...
kdeinit: Aborting. $DISPLAY is not set.
There was an error setting up inter-process communications for KDE. The 
message returned by the system was:

Could not read network connection list.
/home/andrey/.DCOPserver_FreeBSD-amd64.kde.com_NODISPLAY

Please check that the "dcopserver" program is running!
Reusing existing ksycoca

Interesting, when I issue startx, KDE is up and running.
I ran X -configure, and then X -config /root/xorg.conf.new as root; X 
server starts properly, so I copied new config to /etc/X11. I assume my 
problem is KDE related. Errors are about DCOP server, as I can see.
Could anyone help me fix this problem? Thank you in advance!
