New v15 Install X Window Installation

Installing under VMware.  Initial base install goes fine.  Installed VMware
tools first, then Xorg.  Added my login to the Video group.

this command, "To run the X Window System, use startx(1) from x11/xinit, or
install and configure a display manager to start a graphical login on
boot."  Initiating startx does nothing at the prompt.  And where does one
find a display manager.

Is there any resource out there that explains what changes need to be made
to the xorg.conf file for use with VMWare?

Sincere thanks for any replies.
