xf86OpenConsole: Switching VT failed

Hello,

It is Ubuntu 18.04.1 on Windows Subsystem for linux.
      a@W0:~$ cat /etc/lsb-release
      DISTRIB_ID=Ubuntu
      DISTRIB_RELEASE=18.04
      DISTRIB_CODENAME=bionic
      DISTRIB_DESCRIPTION="Ubuntu 18.04.1 LTS"

It is not possible to run the command "startx".
the first time, I found a problem with DBUS, solved this way:
   sudo mkdir /var/run/dbus
   sudo dbus-daemon --config-file=/usr/share/dbus-1/system.conf

Now, I have the error indicated above.
I do not know if it's because of my correction or for some other Reason.
Serious errors are as follows:
   a@W0:~$ cat /var/log/Xorg.1.log | grep EE
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
   [ 12722.394] (EE) systemd-logind: failed to get session: PID 1320 does not belong to any known session
   [ 12722.401] (EE)
   [ 12722.402] (EE) xf86OpenConsole: Switching VT failed
   [ 12722.403] (EE)
   [ 12722.403] (EE)
   [ 12722.404] (EE) Please also check the log file at "/var/log/Xorg.1.log" for additional information.
   [ 12722.405] (EE)
   [ 12722.407] (EE) Server terminated with error (1). Closing log file.

Thank you for your advice
