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.  Oh well, never mind!

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.

Thanks again,
eric
