Now that I finally got xinerama working again (by using MergeFB as an 
Option for my Radeon card), another problem has cropped up.  The 
screensaver isn't running, and when I lock the workstation, I can't get a 
prompt to unlock.  The screen goes to the unlock screen with no prompt.

dbus is running:
root@hostname# dbus-launch
DBUS_SESSION_BUS_ADDRESS='unix:path=/var/tmp/dbus-KbuylYjLnz,guid=500b2b44f8f2f2b68c02568f0755f200';
DBUS_SESSION_BUS_PID=851;

and the socket exists, but there's an extra one:
root@hostname# ls /var/tmp/dbus-*
/var/tmp/dbus-KbuylYjLnz        /var/tmp/dbus-mHCgjDCXI2

which claims to be in use:
root@hostname# dbus-cleanup-sockets
Cleaned up 0 sockets in /var/tmp; 2 sockets are still in use; 0 in unknown 
state

but gnome-screensaver can't find the socket:
root@hostname# gnome-screensaver-command
gnome-screensaver-Message: Failed to connect to the D-BUS daemon: Unable to 
dete rmine the address of the message bus

If I export the session bus address in the terminal, then 
gnome-screensaver-command can connect, and it tells me screensaver is not 
running:
root@hostname# export 
DBUS_SESSION_BUS_ADDRESS=unix:path=/var/tmp/dbus-KbuylYjLnz
root@hostname# gnome-screensaver-command
gnome-screensaver-Message: Screensaver is not running!

Here's log entries germane to screensaver:
root@hostname# grep screensaver /var/log/* | less
/var/log/setuid.today:2103930 -r-sr-sr-x  1 root  wheel   73512 Mar 11 
00:28:00 2006 /usr/X11R6/libexec/gnome-screensaver-dialog
/var/log/setuid.yesterday:2103930 -r-sr-sr-x  1 root  wheel   73512 Mar 11 
00:28:00 2006 /usr/X11R6/libexec/gnome-screensaver-dialog

And to gdm:
/var/log/messages:Mar 29 13:54:16 utd59514 gdm[673]: Error reinitilizing 
server
/var/log/messages:Mar 29 16:14:56 utd59514 gdm[678]: Error reinitilizing 
server

There's nothing else in the logs (AFAICT) to give me a clue what might be 
wrong.

If I lock the desktop, I have to restart gdm (Ctrl-Alt-Backspace) to get 
functionality back, and the console says "gdm[pid]: Error reinitializing 
properly".

Any suggestions as to what to look at next would be appreciated.
