sway-systemd VS dotfiles

This runs Sway in the context of a systemd service, so it will inherit systemd's environment. I use sway-systemd to import stuff like WAYLAND_DISPLAY into the systemd context among other things. My custom env vars are in .config/environment.d which will be loaded by systemd automatically: Sway env, generic Wayland env

Thanks, I had some time and was able to get the service working after following your suggestion. I came across sway-systemd and that along with seeing how you did things made things a lot clearer. The following service should execute the script and let it finish (it finishes in less than a second) before exiting the graphical session, right? Would it be possible to modify it to run it even earlier after killing sway (or right before)? save-desktop-settings.service:

Anyways, I did that to address the same issue with Sway in Fedora and the script should be fully functional with i3. Feel free to try if you're willing to give systemd-oomd another chance. And here is a little extra to go even further and isolate individual windows in tmux.

For what it's worth, I do run Sway as a systemd service, and it works fine. My setup is a bit strange, so I do not recommend trying to duplicate it, but in case it is helpful as a reference, here is my sway.service and how I import environment variables before starting it.

For example, here's me running my colortest function inside and outside of Neovim's terminal: https://imgur.com/a/7YyTzj9. Note that Neovim's idea of "black" is actually black, whereas in my terminal's colorscheme I have it set as a gray color.
