Don't you need XWin and dbus running and env vars set, the following files, get 
a clean OK from cygcheck, or be able to rerun the postinstall script:

$ ls -lgo /etc/machine-id /var/lib/dbus/machine-id /etc/postinstall/dbus.sh.done
lrwxrwxrwx  1 26 May 14  2013 /etc/machine-id -> ../var/lib/dbus/machine-id*
-rwxr-xr-x+ 1 33 May 14  2013 /var/lib/dbus/machine-id*
-rw-r--r--  1 54 Aug  9  2017 /etc/postinstall/dbus.sh.done
$ head /etc/postinstall/dbus.sh.done
mkdir -p /var/lib/dbus
/usr/bin/dbus-uuidgen --ensure
$ cygcheck -chv dbus
