It is my second day in \*nix world and search didn't help me to solve my issue. [This question here is not relevant either.](https://unix.stackexchange.com/questions/322527/could-not-start-d-bus-can-you-call-qdbus)  

I installed FreeBSD 11 and I installed KDE.

```
pgk install kde

```

I tried to run it like

```
startkde

```

but turns out that I also need X server to run a UI. Ok. So I installed it like

```
 pgk install xorg

```

Now I'm running X with "startx" and then I'm running KDE with "startkde"
and I'm getting

**Could not start d-bus. can you call qdbus?**

How I can call qdbus? What's that?

Update 1
--------

As was suggested I edited `rc.config` and added

```
dbus_enable=YES

```

result is the same

Update 2
--------

I followed [§5.7.2 of a handbook](https://www.freebsd.org/doc/en/books/handbook/x11-wm.html) and
`/proc` was mounted by adding this line to `/etc/fstab`:

```
proc           /proc       procfs  rw  0   0

```

`/etc/rc.conf` was edited and now has three lines:

```
dbus_enable="YES"
hald_enable="YES"
kdm4_enable="YES"

```

Now if I'm running `startkde` I'm getting error:

```
"display is not set or cannot connect to x server" 

```

I found somewhere that I need to execute

```
type plasma-desktop #kde4

```

to check if `plasma-desktop` is installed, and looks like it is fine. Not sure about kde. Here it is:
