could not start dbus

I am not exactly sure when this happened but it was sometime after I tried adding
pkg networkmgr. Now when KDE starts I see

Could not start DBUS

I have
Code:
dbus_enable="YES"
in /etc/rc.conf as well as
Code:
hald_enable="YES"
and running
sudo service dbus start
in terminal returns
dbus already running? (pid=899)

top tells me that pid 899 is USERNAME messagebus and COMMAND is dbus-daemon.
KDE will not start but TWM does and I can run Firefox and other programs in a terminal

I am not seeing anything helpful in the log files and after reading through the forum
for a couple of hours I am not able to fix things.

can anyone point me in the right direction?
I am new to FreeBSD and am still learning.
Thanks in advance

How are you starting KDE?
After computer boots, I get a splash screen saying "Welcome to FreeBSD at computername" and then enter user ID and password. I am assuming this calls /usr/local/bin/startkde.
If I type /usr/local/bin/startkde in a terminal, I get the same message "Could not start D-bus. Can you call qdbus?"
 
Ok, that's good. If you started KDE by hand you would have to take care to start a proper session. But KDM should start a proper DBUS session but apparently it has problems with that. Have you tried restarting DBUS? It may just be stuck (running but not accepting anything). Stop DBUS; service dbus stop. Then check if all DBUS processes are gone; pgrep -f dbus. Kill the left-overs if there are any. Start DBUS again: service dbus start.

Stopping and restarting does not work and in trying to fix I have made things worse.
I now just get a blank splash screen at boot. I can log in as single user and disable kde - restart and login, but cannot start x. I would like to fix rather than re-install everything.
 
Does your system have the file /etc/machine-id ?
dbus seems to not generate one under all circumstances.
If not, generate a dbus machine-id with below and re-try.
# /usr/local/bin/dbus-uuidgen

This did not help.
This might be a dumb question but where is the configuration for X kept?
I read that we no longer use a xorg.conf file in FreeBSD 11.0.
I can log in as root and start X, and run startkde from a terminal, but my regular user cannot start X.
User is in group wheel.
I would think that I need to get X to work before anything else.
I don't see anything in the Xorg.log.0 file that is helping me other than the X server fails to start with error 1.
 
I can log in as root and start X
Yeah, don't do that (under nomal conditions)

The topic was "could not start dbus", so I assume you checked that dbus started as suggested by SirDice ( pgrep -f dbus)?

Is your user member of group video? When logged in, check with $ id
If you're not a member add with:
# pw group add -g 44(?) -M <your-user>
(?) for video group ID - check from /etc/group
 
Yeah, don't do that (under normal conditions)
Only did that to test
Is your user member of group video
There is no video group - never was. Manual tells me that I just need to be member of group wheel.
This started as not being able to start kde, but after messing with things I cannot start X.
 
I added a new user to test and made member of wheel and didn't work
I also compared Xorg.0.log to Xorg.0.log.old and they are the same up to a point.
I copied them to a pen drive so that I could go to another computer and post it here.
This is where the files differ and where I think things go wrong.
