The best way is to have user's .xsession files be login sessions.
Assuming bash:

  #!/bin/bash --login
  exec x-session-manager

Make sure it is executable or it will have no effect.

  chmod a+x $HOME/.xsession

But you will immediately see the problems of trying to do that
globally.  Do all users use bash?  Probably not.  That is just the
beginning.

Read /etc/X11/Xsession and /etc/X11/Xsession.d/* for details of X
startup especially 50xfree86-common_determine-startup and the option
allow-user-xsession from /etc/X11/Xsession.options.  By turning that
off and forcing users into a particular shell then you can turn on
--login for them forcibly.  Obviously this has severe undesirable
effects.
