Is there a way for emacs to receive display changes notification from the windows manager? I understand this might be an OS dependent question, so I'm particularly interested in the interaction between emacs and Gnome 3 windows manager (on Linux of course).
I'd like emacs to invoke certain functions when such event occurs.
C-h i g (elisp)Window Hooks
is sufficient? (n.b. Lots of changes in that area in 27.1). I can't tell what "changes display" means, btw. – phils Sep 16 '20 at 21:11
