When it fires

Section titled “When it fires”

This fires from X11Helper.configureGraphicsEnvironment(...), called right before the Minecraft process is started, only when all of the following are true:

  1. The launcher is running on Linux (os.name contains linux).
  2. The child process environment doesn’t already have a DISPLAY variable set (i.e. you haven’t already configured one yourself).
  3. Minified can find an active X11 socket in /tmp/.X11-unix (e.g. X0, X1, …) and derive a display string like :0 from it.

If any of those conditions fail - most commonly on Windows/macOS, or on a pure Wayland session with no Xwayland socket available - this event simply never fires and DISPLAY is left untouched.

When it does fire, Minified also sets DISPLAY on the child process environment to the resolved display value and, if WAYLAND_DISPLAY was set, removes it and sets XDG_SESSION_TYPE=x11 so Minecraft’s LWJGL/GLFW windowing picks X11 instead of trying (and often failing) to use Wayland directly.
