  This is a bare bones synopsis of the events that occur when you log
  in to the console via xdm (the default method of logging in) under
  IRIX 4.0.x and, with the desktop *disabled*, IRIX 5.x.

   1) Provide a "failsafe" (nographics) login if required/requested.
   2) Exec $HOME/.xsession if it exists. If it exists, the remaining
      steps should normally be included in the users .xsession file
      as well.
   3) Load $HOME/.Xresources if it exists.
   4) Set XUSERFILESEARCHPATH.
   5) Incorporate a "shell" environment into the "session".
      (man userenv)
   6) Set the root background and cursor.
   7) Disable display access control (xhost +).  (man xhost)
   8) Start 4Dwm.
   9) Wait for 4Dwm to come up.
  10) Start the console.
  11) Execute $HOME/.sgisession if it exists.
  12) Start WorkSpace if the user wants it.
  13) Put a Toolchest on each screen.
  14) Exec the "reaper". (man reaper / endsession)
