Ironically, I started using Sway, and Wayland, and dropped a session or login manager, and felt ready to drop the xserver… When I rebooted, everything seems to work. The terminal. Firefox. But hilariously, dmenu no longer works: "cannot open display".
Well, now I'm trying to build emacs-29 and when I run ./configure it says:
>
configure: error: cannot find required auxiliary files: ndk-build-helper.mk
Uh…
