Thank you!

As far as I know, the devilspie2/.emacs solution that I figured out, is 
the /only/ way to make emacs behave like `emacs -mm` right now. Both of 
them will:

* Always run the settings regardless how emacs is opened (e.g. Alt+F2 in 
MATE) despite that an external program (devilspie2) is used.

* The buffer will:

** Expand automatically when emacs opens

** Expand quickly like `emacs -mm`

* Like `emacs -mm`, the size of ~/.emacs does not impact the time it 
takes to expand the buffer.

This makes the devilspie2 solution unique, since all solutions at 
https://www.emacswiki.org/emacs/FullScreen makes the buffer expand 
slowly. That's why I suggest that we should add my devilspie2/.emacs 
solution to 
https://www.gnu.org/software/emacs/manual/html_node/efaq/Fullscreen-mode-on-GNU-Linux.html
