Well, not necessarily: I would have thought that invoking exwm-enable would set some flag (i.e. an elisp global variable) but it does not look like it does, having gone through the code.

Again, for the record, as I do not use a desktop environment, this variable is set to "lightdm-session" regardless of the window manager I start up from my .xsession file. But thank you for your suggestions. I've gone with (getenv "WM") in my .emacs, where WM is the environment variable I use in my .xsession to store the name of the window manager I choose during startup of the X session. I just had to make sure I "exported" that variable. Very easy and pretty much what you were suggesting except with my own variable.
