use Xdefaults to configure emacs

• Create a new .Xdefaults file in your home directory. This file can be used to configure your emacs.
  

  
  Emacs.Font: fontset-courier
  Emacs.Fontset-0:-*-courier-medium-r-normal-*-18-*-*-*-*-*-fontset-courier,\
  emacs.geometry:90x60+200+200
  emacsp.background:gray75
  
  Emacs.foreground:  gray
  Emacs.background:  black

  Then you can do this to make it work.
  

  
  xrdb .Xdefaults
