# Starting

First, try running `cargo run` in a terminal window. If a headset is plugged in and OpenXR is working no window will show up. However, the headset should show the same things as the window that opens:

### Images
Flatscreen mode upon initial startup:

XR mode when OpenXR somehow fails:

### Startup Scripts

`stardust-xr-server` is a Wayland server which clients can connect to.
The easiest way to get Wayland applications to connect is to run a script with your initial environment.
This can be specified using the `-e or --execute-startup-script <PATH>` CLI argument, or can be placed in `$HOME/.config/stardust/startup`.
(assuming you have cloned and installed [flatland](https://github.com/StardustXR/flatland))

This example will spawn the flatland client which will help arrange 2D windows, and spawn a KDE konsole which will attach to the wayland display set up by stardust. You will then be able to drag the konsole around with your mouse. If you have a keyboard you can move your camera around with `Shift+WASD`. If you don't have a 6DoF controller connected you can also use your mouse to move a hand around and the scroll wheel to move it towards and away from your screen.

```
#!/bin/sh

echo $DISPLAY;
echo $WAYLAND_DISPLAY;
