I periodically watch the status of Lanzaboote [1] to know when it will be upstreamed to Nixpkgs so that it will be easier for people (e.g. me) to switch to NixOS. It has been funded by the Next Generation Internet initiative that the article says is being eliminated.

Some weeks ago I searched for a more general solution that doesn't depend on the compositor and doesn't need root (i.e. an xkill replacement), but I didn't find one.

As a frequent user of xkill I was surprised by that too, but I remember reading somewhere that making a terminal application kill another application's window is not allowed by design. Reusing a sibling commenter's analogy, it's kind of like some javascript functions in the browser can only be triggered by user actions for security reasons.

The compositor, however, is allowed to kill the windows it's showing. So if you want to kill a window, you can ask the compositor to do it for you. Gnome, KDE [0], sway [1], etc.. each expose this functionality in a way that differ between each other.

Under Wayland with Gnome (it's gnome-specific), I recently learned you can kill windows by using Looking Glass:

  // 1. Open looking glass: Alt+F2 > lg
  // 2. Use picker to pick window (button on the top left corner).
  // 3. Now an object r(0) of type MetaSurfaceActor is available in the
  //    gjs console (or some other number if you've already used it).

  // To get pid:

  r(0).get_parent().get_parent().get_meta_window().get_pid()

  // To kill window and process:
  
  r(0).get_parent().get_parent().get_meta_window().kill()

Reference for what those .get_parent() refer to: https://gitlab.gnome.org/GNOME/mutter/-/tree/fc1de744/src/co...
