alt Hacker NewsThanks to EXWM (not mentioned here), emacs has been my literal X window manager for several years. I installed it as a lark, thinking there's no way this will work properly, and just never stopped using it. It's brilliant.

You can also use EXWM in Xephyr, so you can have an emacs window with its own controlled windows instead of replacing the whole DE/window-manager. I suppose this doesn't work with multiple frames though.
I have been experimenting with xdotool windowmap/windowunmap and override_redirect (and maybe LD_PRELOAD?) to try get something like EXWM to work without creating another X server, by capturing windows. I'm doing this in vim though.
By the way, neovim has an apparently working EXWM-like plugin, NXWM/nwm: https://github.com/altermo/nwm
Me too. Only having issues with floating windows so far.
EXWM is great, having the same flow to manage X applications as for emacs buffers is a huge benefit. My only concern is if X11 will be maintained sufficiently into the future to keep using it, currently there is no Wayland support in EXWM.
