Launching Godot Games on Steam Deck from the command line via Remote Shell
For some reason, my Godot game would no longer launch on the Steam Deck. I could hear it running as if it were running in the background, but the screen kept showing the Steam Deck’s UI.
Since it’s all Linux I figured it should be possible to just drop to the command line and launch a game from there. Linux typically uses the DISPLAY environment variable to tell the application where its output should be shown. And it turns out, it worked exactly as expected.
In the Steam Devkit Management Tool, there’s a
Remote Shell
button.
Once the shell is launched, I was curious about the OS:

The location where Steam keeps its games is somewhat hidden:

But a devkit game won’t be found there. It’s in the “devkit-game” directory instead:
And it’s running. Launching games via the command line works well, and this may be great for debugging slightly more complex issues during launch, especially when attaching a debugger, or even when passing arguments to trigger specific scenarios on an actual device.
We can take this up to another level. How about sharing your PC’s mouse and keyboard with the Steam Deck? Let’s go.
One of the benefits of working with Godot Engine is that GDScript allows one to operate high level. GDScript is dynamically typed, so not even variable types have to be specified, but I would strongly recommend using static typing wherever possible. It can help with performance but primarily adds clarity when trying to follow the …
Normally I use OBS for screen recording, but there are cases where it makes sense to use Godot’s built-in movie writer that was recently announced. For example, if you have a slow PC or really demanding game, OBS will skip frames. It makes sense since OBS is just recording what’s on the screen in real …
I use an app called barrier. It allows you to share your mouse and keyboard with multiple devices. I use it, because I tend to have my laptop and Macbook sitting next to my PC, and it makes working across all devices very convenient. It’s a mix of a multi-monitor and multi-computer setup.

To run a game, go to the devkit directory where your game is and run it from the command line:
In Linux, output goes to the device specified via the DISPLAY env var. When connecting to the Steam Deck via shell, that is missing, hence the error.
Let’s run it again, with the DISPLAY environment variable set to the first device:
